An electric dipole placed in a non-uniform electric field can experience
Option: 1 a force but not a torque.
Option: 2 a torque but not a force.
Option: 3 always a force and a torque.
Option: 4 neither a force nor a torque.
An electric dipole placed in a non-uniform electric field can experience both torque and force. Since the electric field is non-uniform the net force is non zero.
