Question
An electric dipole with moment p is placed in an ideal parallel-plate capacitor, off cent shown. I there a net electric force on the dipole? Is there a net electric torque? There is a net electric force to the left, and there is a clockwise net electric torque. There is no net electric force, but there is a counter-clockwise net electric torque. There is a net electric force to the left, there is a clockwise net electric torque. There is a net electric force to the left, and there is a counter-clockwise net electric torque.Explanation / Answer
The parallel plate capacitor has a uniform electric field between the plates. So if we put a dipole in a uniform electric field the dipole will feel a torque but no net force. So here in this case the net force on the dipole is zero and the torque is clockwise. So the answer is option (d)
