Question

An electric dipole is placed in non- uniform electric field, then it experiences
A. Only torque
B. Force and torque
C. Only force
D. Neither force nor torque

Answer 1

Hint: In all kinds of questions you will learn the fundamental essence of the electric dipole as it is put under the influence of a non-uniform electric field or what kinds of force it encounters.

Complete Step-by-Step solution:
According to the given statement the electric field is not uniform. 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. it is seen that when p is parallel to E, dipole has a net force in the direction of growing field, and when p is anti-parallel to E, the net force on dipole I in the direction of decreasing field. Power depends on dipole mom’s orientation.
Hence, option B is correct.

NOTE: The word electrical dipole moment we used in the above explanation can be defined as a measure of the difference between positive and negative electrical charges within a system, i.e. a measure of the system's overall polarity. The SI units at the moment of the electric dipole are coulomb-meter.
