Answer:
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.
Hence, an electric dipole placed in a non-uniform electric field experiences both a torque and a net force.
