Once W is known, the force between the spheres is given by
F=−∂
c
W
(or by −∂
s
W).
What is the force between two charged spheres having charges?
Hint: The force between two small charged spheres is
directly proportional to the charge on both the spheres
and inversely proportional to the square of the distance between them.
What is the force between two?
F/l
is the force per unit length between two parallel currents I
1
and I
2
separated by a distance r. The force is attractive if the currents are in the same direction and repulsive if they are in opposite directions. This force is responsible for the pinch effect in electric arcs and plasmas.
How do you find the force of a sphere?
fSolid sphere=GmMsphereD2
. (18) Equation (18) tells us that a sphere of mass M and radius D exerting a gravitational force on a point-mass m outside of the sphere exerts the same force as a particle of mass M acting on the point-mass m such that those two particles separation distance are given by D .
Is the force the same for both spheres or different?
The amount of air resistance on a falling object depends on how fast it is falling and on the shape of the object. Because the metal spheres in your problem are the same size and shape, the
air resistance force on them will be the same
(if they are falling at the same speed).
How far apart should the 2 electrons be if the force?
Hence, the distance of separation is equal to
0.117m
.
What is the force between two alpha particles?
The force between two alpha particles separated by a distance ‘r’ is
F.
In order to have same force the distance between single ionized chlorine atoms separated by a distance of.
What is the force between two small charges of?
Hence, force between the two small charged spheres is
6 × 10
– 3
N
. The charges are of same nature. Hence, force between them will be repulsive.
What is the force between two small charged spheres having charges of 2/10 7 C?
Hence,
force between
the
two small charged spheres
is 6×10−3 N. The
charges
are of same nature. Hence,
force between
them will be repulsive.
What is the force on the second sphere due to the first?
(b) What is the force on the second sphere due to the first? The distance between the two spheres is 0.12 m. (b) Both the spheres attract each other with the same force. Therefore, the force on the second sphere due to the first is
0.2 N
.
What is the force of a sphere?
The gravitational force on an object within
a hollow spherical shell is zero
. The gravitational force on an object within a uniform spherical mass is linearly proportional to its distance from the sphere’s center of mass (COM).
How much charge is on each sphere?
A sphere has a net excess charge of
-4.8 x 10-19 coulomb
. The sphere must have an excess of 44.
What is the final charge on each sphere?
What is the net charge on each sphere now? When the spheres are touched the net +4Q charge will spread out evenly over the two spheres. Each sphere will have a net charge of
+2Q
.
Will two spheres with different masses fall towards earth at the same rate?
Because Earth gives everything the exact same acceleration, objects with different masses will still hit the ground at the same time if they are
dropped
from the same height. … If two objects were dropped on the moon, where there is no air, they would fall at the same rate no matter how much they differ in mass.
How will the force between two spheres change if the distance between two spheres doubles?
The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker,
decreasing to one-fourth of the original value
. … The size of the force is proportional to the value of each charge.
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.
