Question

An electric dipole kept in a uniform electric field experiences :

• A. Force and a torque
• B. A force, but no torque
• C. A torque but no force
• D. Neither a force nor a torque

Answer 1

The correct option is C A torque but no force

In a uniform electric field, both the point charges comprising the dipole will experience force, equal in magnitude and opposite in direction.
Though the net force will always be zero, the torque will be in same direction for both the charges. Hence torque will not be zero.
