When an electric dipole is placed in a uniform electric field, it experiences. An electric dipole placed in uniform electric field experiences
a torque which align the dipole parallel to the direction of the electric field with
zero net force.
What happens when we keep a dipole in a uniform external electric field?
When an electric dipole is placed in a uniform field, it
experiences a torque
. This torque tries to align the dipole in the direction of the field.
When a dipole is placed in an uniform external field?
Even if we change the orientation, the length and the charge of the dipole, the net force on the dipole will be equal to zero. Hence, the electric force on a dipole when it is placed in a uniform electric field
is always zero
. So, the correct answer is “Option A”.
What happens to the dipole if we place in an external field?
It is interesting to learn that, a dipole placed in an external electric field
acquires a rotating effect
. This rotating effect is termed as ‘torque’ felt by the dipole. Excitingly, the net torque can be calculated on the opposite charges present in a dipole for estimating the overall rotation.
What will happen when dipole placed in uniform magnetic field?
When a magnetic rod, (which can be taken as a magnetic dipole), is kept in a uniform magnetic field,
the North Pole senses a force equal to the multiplication of the magnetic field intensity and the pole strength in the magnetic field direction.
When a uniform field is a dipole experience?
Now, In a uniform electric field, both the point charges comprising the dipole will experience force,
equal in magnitude and opposite in direction
. Though the net force will always be zero, the torque will be in the same direction for both the charges. Hence torque will not be zero.
At what position is the electric dipole in uniform electric field?
When a dipole is immersed in a uniform electric field, as illustrated in Figure 16.4. 3, the
net force on the dipole is zero
because the force on the positive charge will always be equal and in the opposite direction from the force on the negative charge. Figure 16.4. 3: An electric dipole in a uniform electric field.
When a dipole is placed in an external electric field it will be?
1: A dipole in an external electric field. (a) The
net force on the dipole is zero
, but the net torque is not. As a result, the dipole rotates, becoming aligned with the external field.
When an electric dipole is held at an angle in a uniform electric field?
1) the forces experienced by the 2 charges constituting the electric dipole when placed in an uniform external electric field are equal and opposite in nature, the
net force on the dipole is zero
. No torque act on the dipole when the moment of electric dipole is parallel to the electric field.
What would happen if the external field E is increasing parallel to P?
In the first case, the electric field is increasing parallel to ‘p’. Thus that means the
electric field on the positive charge will be larger than that on negative charge
. Hence positive charge will experience more force than negative charge. … Hence negative charge will experience more force than positive charge.
How does a dipole behave in electric field?
In an electric field a dipole
undergoes a torque, tending to rotate so that its axis becomes aligned with the direction of the electric field
. … The electric dipole moment, a vector, is directed along the line from negative charge toward positive charge.
What is dipole moment in electric field?
tendency to rotate in an electric or magnetic field) and is therefore called polar. The dipole moment (μ) is defined as the product of the magnitude of the charge, e, and the distance separating the positive and negative charges,
l: μ = el.
What is energy of dipole in electric field?
Consider a dipole with charges q1 = +q and q2 = -q placed in a uniform electric field as shown in the figure above. … From the above equation, we can see that the potential energy of dipole placed in an external field is
zero
when the angle Ɵ is equal to 90° or when the dipole makes an angle of 90°.
What is a uniform magnetic field give an example?
Uniform Magnetic Field: Magnetic field is said to be uniform if the magnetic induction has the same magnitude and the same direction at all the points in the region. … An example of the uniform magnetic field over a wide area is
the Earth’s magnetic field
.
What happens to a dipole in a non uniform magnetic field?
or in general, any magnetic dipole placed in a non-uniform B-field: Thus, there is a force acting on a dipole when placed in a non-uniform magnetic field. … Thus, the
force on loop 1 from the non-uniform field of loop 2
is directed up, and we see that there is an attractive force between them. North-South attract!
Does a magnetic dipole experience?
If a dipole is placed in a uniform magnetic field,
it experiences a torque but no force
. When a dipole is placed in a non uniform electric field, it experiences a non zero net force as well as torque. a dipole will rotate to align with an uniform electric ?
