Question

An electric dipole in a uniform electric field experiences (When it is placed at an angle `theta` with the field)
A. only a force but not torque
B. only a torque but no net force
C. both, a torque and a net force
D. no torque and no net force

Answer 1

Correct Answer - c
An electric dipole is a system of two equal and opposite point charges separated by a small distance. When placed in a non-uniform electric field the two poles experience unequal forces. As the dipole will feel two forces which are although opposite but not equal. It meand the net force will be there and these forces act at different points of body. A torque is also there.
