# When an electric dipole is placed in an non uniform electric field than torque on the dipole will be?

Contents

When an electric dipole is placed in a non uniform electric the net force on the dipole due to the electric field will be non-zero as well as the torques it experiences in the field will be non-zero.

## What will happen if an electric dipole is placed in a non-uniform electric field?

If an electric dipole is placed in a nonuniform electric field, then the positive and the negative charges of the dipole will experience a net force. And as one end of the dipole is experiencing a force in one direction and the other end in the opposite direction, so the dipole will have a net torque also.

## When an electric dipole is kept in a non-uniform electric field torque acting on it may be zero?

The direction of electric dipole moment is from negative to positive charge. Hence the resultant force will always be non-zero. Therefore option A and C are incorrect. In case the electric dipole gets parallel or antiparallel to the electric field then the torque will be zero.

## What happens when an electric dipole is held in a non-uniform electric field what will be the force and the torque when the dipole is held parallel or antiparallel to the electric field?

Neither force nor torque. … So, when the electric field is not uniform then the net force will be non-zero and there will also be torque on the following system. If the dipole moment p is parallel or antiparallel to the external field E, the net torque is zero but there is a non-uniform force on the dipole E.

## What happens if the electric field is non uniform?

On the other hand, if the electric field is nonuniform, the force on each of the two poles of the dipole is not equal; therefore, the net force is not equal to zero and there is movement of the particle. Furthermore, when a polarizable object is subjected to an electric field, a dipole moment is induced.

## What will happen if electric field is not uniform?

(ii) In case of non-uniform field, force acting on both the ends will not be equal. So, they will act as combination of couple and a net force. In this way, dipole will have both rotational as well as linear motion.

## When an electric dipole is held at an angle in a non uniform electric field?

Electric dipole will experience a torque when dipole vector is not parallel to electric field direction. The torque τ = p × E = pESinθ. when p and E are parallel then angle θ between the two vectors is zero, hence there will not be any torque.

## 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.

## 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 happens when a dipole is placed in an electric 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.

## 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.

## When an electric dipole is held at an angle in a uniform electric field the net force and torque on the dipole is?

Answer: 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.
