A solid conducting sphere holds more charge
than
a hollow sphere of the same radius when they are at same potential. A solid conducting sphere hold more charge than a hollow sphere of same radius.
Can a solid conducting sphere hold more charge than hollow sphere of same radius explain?
So for charges
there is no difference
between a hollow and a solid conducting sphere. Originally Answered: A solid sphere and a hollow sphere having same radius will hold same maximum charge .
Will a solid metal sphere hold a larger charge than hollow sphere of same diameter where does the charge reside in each case?
A
solid sphere does not retain more charge than
a hollow sphere of the same diameter, because charge resides on the outer surface of a conductor, and outer surface areas of the two spheres are equal.
What is the excess charge on a conducting sphere?
SO: charges in a conductor redistribute themselves wherever they are needed to make the field inside the conductor ZERO. Excess charges are always on the surface of the conductors. A spherical conducting shell has an excess charge of
+10 C.
A point charge of −15 C is located at center of the sphere.
Can a solid conducting sphere?
A solid conducting sphere, having a charge Q, is surrounded by an uncharged conducting hollow spherical shell. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V.
Can a conducting solid sphere hold charge at its Centre explain your answer both in case of a single charge and for multiple charged particles?
Both the spheres will hold same maximum charge
.
Which of the following is not the unit of charge?
Ampere per second
– It is not the unit of charge.
Why the potential of a body connected to earth is taken to be zero?
Since there is a potential gradient existing between the negative charges on the earth and the positive charges in the atmosphere, a current can flow from the atmosphere to the surface of the earth which neutralises the negative charges on the earth
. … So the potential associated with the earth is taken as zero.
Can an electric potential exists at a point in?
Yes
. The electric field might be generated for example by two charges: +5C and −4C separated by 2 meters. There is a point in between them where the potential is 0 (the electric potential is also 0 in the infinite) but in that point the electric field vector is not null.
Why is there no charge inside a conducting sphere?
The lowest potential energy for a charge configuration inside a conductor is always the one where the charge is uniformly distributed over its surface
. This is why we can assume that there are no charges inside a conducting sphere.
How we explain electric field of charge in hollow sphere and solid sphere?
Electric Field Of Charged Hollow Sphere
The
conducting hollow sphere is positively charged with +q coulomb charges
. If the sphere has equal density all over its surface , then +q charge will be equally distributed all over the surface. So, the entire system is a symmetric system. … E is constant through the surface .
Can a solid conducting sphere hold more charge than a hollow sphere?
A solid conducting sphere holds more charge than a hollow sphere of the same radius when they are at
same
potential. A solid conducting sphere hold more charge than a hollow sphere of same radius.
What is the excess charge on a conducting sphere of radius r 0.15 m if the potential of the sphere is 1400 V and V 0 at infinity?
2.5×10−8C
.
Is conducting sphere a hollow sphere?
A conducting hollow sphere will have the
entire charge on its outer surface
and the electric field intensity inside the conducting sphere will be zero. For a spherical charged Shell the entire charge will reside on outer surface and again there will be no field anywhere inside it.
Where is the charge on a conducting metal sphere present?
Answer: Correct option is a)
On the surface of sphere
.
The
force acts along the line joining the centers of the spheres
. Because the same type of charge is on each sphere, the force is repulsive. As expected, the force between the charges is greater when they are 3.0 cm apart than when they are 5.0 cm apart.
What happens when two conducting spheres touch?
When the two conducting spheres are brought together to touch, it is as though
they become one single big conductor and the total charge of the two spheres spreads out across the whole surface of the touching spheres
. When the spheres are moved apart again, each one is left with half of the total original charge.
How much is a faraday?
The faraday is a dimensionless unit of electric charge quantity, equal to approximately 6.02 x 10
23
electric charge carriers. This is equivalent to
one mole
, also known as Avogadro’s constant . In the International System of Units ( SI ), the coulomb (C) is the preferred unit of electric charge quantity.
Why does excess charge lies on the surface of a conductor?
The inside of a conductor cannot contain any net charge. Such charges would produce a field inside the conductor, and electrons would move and cancel out the field and neutralize the charge. Any excess charge on
a conductor must therefore reside on the surface
.
Is faraday unit of charge?
Related to Faraday’s constant is the “faraday”,
a unit of electrical charge
. It is much less common than the coulomb, but sometimes used in electrochemistry. One faraday of charge is the magnitude of the charge of one mole of electrons, i.e. 96485.
What is not true about electric charge?
Answer: D is not true charge of one electron is
not
one coloumb. Coulomb is very big unit of charge.
Can a body have electric potential and still be uncharged?
Yes
, but not always.
Can a body have charge and still be at zero potential?
Yes,
it is possible
. The object must be grounded, then the potential of the object will be zero but not the charge.
Is earth an insulator?
Earth is a good conductor
. … The parts of the earth where there is no moisture acts as an insulator. The parts of the earth where there is moisture acts as a good conductor.
Can electric potential be zero but not electric field?
Yes
, electric potential can be zero at a point even when the electric field is not zero at that point. … At the midpoint of the charges of the electric dipole, the electric field due to the charges is non zero, but the electric potential is zero.
Can an electric field be zero?
There is no zero-field point
for a pair of equal-magnitude-but-opposite-sign charges. Electric field is zero in that point because the sum of electric field vectors have same intensity and direction, but are opposite. That point is halfway between two like charges.
What is the electric field inside a conducting sphere that contains no enclosed charges?
1. uniformly charged means, chargess are distributed on the surface of the spherical uniformly. but inside the sphere there is no charge so the electric flux is zero, so
electric field is zero
..
Is there any charge inside the conductor?
The inside of the conductor does not contain any charge
. If charges were present inside a conductor then such charges would produce an electric field and the electrons would move and cancel out the field neutralizing the charge.
What happens to the potential energy when the magnitude of the charges increases?
Increasing the -ve charge makes the potential energy increase in magnitude (the
force becomes stronger
) but decrease in sign (the force becomes more attractive).
What is Gauss law in electrostatics?
Gauss’s law for electricity states
that the electric flux across any closed surface is proportional to the net electric charge enclosed by the surface
. The law implies that isolated electric charges exist and that like charges repel one another while unlike charges attract.
Is there charge inside a conducting sphere?
Gauss’ law tells us that
the electric field inside the sphere is zero
, and the electric field outside the sphere is the same as the field from a point charge with a net charge of Q. This result is true for a solid or hollow sphere. So we can say: The electric field is zero inside a conducting sphere.
When the electric charge are at Infinity equipotential surface are?
Explanation: If a point charge is situated at infinity, the electric field lines coming out of it will be in the form of parallel straight lines. As we know that field lines cut the equipotential surfaces orthogonally, therefore the equipotential surfaces must be
plane surfaces
.
What is electric field formula?
An electric field is also described as the electric force per unit charge. The formula of electric field is given as;
E = F /Q
.
What is the strength of the electric field inside the conducting sphere?
Gauss’ law tells us that the electric field inside the
sphere is zero
, and the electric field outside the sphere is the same as the field from a point charge with a net charge of Q. This result is true for a solid or hollow sphere. So we can say: The electric field is zero inside a conducting sphere.
Why is there no charge inside a hollow conductor?
So, the
electric field inside any hollow conducting surface is zero provided
that there are no charges enclosed by that region. In electrostatics free charges in a good conductor reside only on the surface. So the free charge inside the conductor is zero.
What is the difference between conducting sphere and non conducting sphere?
The difference between a conducting and non-conducting sphere is that
the charge is present only on the surface for a conducting sphere
but for a non-conducting sphere, it is uniformly distributed. Due to the same reason, the electric field due to both spheres will be very different.
Can a conducting solid sphere hold charge at its Centre explain your answer both in case of a single charge and for multiple charged particles?
Both the spheres will hold same maximum charge
.
Will a solid metal sphere hold a larger charge than hollow sphere of same diameter where does the charge reside in each case?
A
solid sphere does not retain more charge than
a hollow sphere of the same diameter, because charge resides on the outer surface of a conductor, and outer surface areas of the two spheres are equal.
What is the charge when a conductor is charged?
The electric field lines either begin or end upon a charge and in the case of a conductor,
the charge exists solely upon its outer surface
. The lines extend from this surface outward, not inward. This of course presumes that our conductor does not surround a region of space where there was another charge.
What is a solid conducting sphere?
A solid conducting sphere, having a charge Q, is
surrounded by an uncharged conducting hollow spherical shell
. Let the potential difference between the surface of the solid sphere and that of the outer surface of the hollow shell be V.
What does a conducting sphere mean?
Explanation: Conducting Sphere : A conducting sphere
will have the complete charge on its outside surface and the electric field intensity inside the conducting sphere will be zero
. For a spherical charged Shell the entire charge will reside on outer surface and again there will be no field anywhere inside it.
What is difference between solid sphere and hollow sphere?
In a hollow sphere all the small particles are located far away from its centre due to which its moment of inertia increases due to this it needs
50% more torque
and in case of solid sphere it has less moment of inertia so less torque required to rotate it to the same extent as that of hollow sphere.
