Question
We have two electric dipoles. Each dipole consists of two equal and opposite point charges at the end of an insulating rod of length d. The dipoles are placed along the x-axis at a large distance r apart oriented as shown below:
The dipole on the left
- will feel a force upwards and a torque trying to make it rotate clockwise
- will feel a force upwards and a torque trying to make it rotate counterclockwise
- will feel a force upwards and no torque about its centre.
- will feel a force downwards and a torque trying to make it rotate clockwise.
The correct answer is: will feel a force upwards and a torque trying to make it rotate counterclockwise

A nonconducting ring of radius R has two charges q and q/2 distributed uniformly on two half of it. A negative charge q/2 (mass = m) is placed at a distance R from the centre of the ring on its axis at a point P and released. If this charge is restricted to move freely only along the axis of the ring, find the speed of this charge when it crosses the centre of the ring
