Question

Can anyone please tell me about the torque on a electric dipole in a non uniform electric field??​

Answer 1

Explanation:

When electric field is not uniform, the net force will be non-zero, there will also be torque on the system.

When dipole moment p is parallel or anti-parallel to external field E, the net torque is zero, but there is a force on the dipole E which is not uniform. It is seen that when p is parallel to E, dipole has a net force in the direction of increasing field and when p is antiparallel to E, the net force on dipole is in the direction of decreasing field. Force depends on the orientation of dipole moment with respect to the external field.

Answer 2

Answer:

Thus, for an ideal (point) dipole in a non-uniform electric field, the torque is given by the same formula as that of a uniform field. ... When p and E are parallel and anti-parallel, the torque is zero, so yes zero is possible.
