An electric dipole is placed at an angle of $${30^ \circ }$$ to a nonuniform electric field. The dipole will experience

A. a translational force only in the direction of the field

B. a translational force only in a direction normal to the direction of the field

C. a torque as well as a translational force

D. a torque only

Answer : a torque as well as a translational force

Solution :
Electric Field mcq solution image

The electric field will be different at the location of the two charges. Therefore the two forces will be unequal. This will result in a force as well as torque.
