Detailed Solution

Concept: According to the statement, the electric field is not uniform. As a result, when the electric field is not uniform, the torque on the following system exists, and the net force is also non-zero.
If the dipole moment p is parallel or antiparallel to the external field E, the net torque is zero, but there is an uneven force acting on the dipole E. When p is parallel to E, the dipole experiences a net force directed toward the expanding field, and when p is anti-parallel to E, the dipole experiences a net force directed toward the contracting field. The direction of the dipole has a significant impact on power.
Hence, the correct option is 2.
