When a p-type impurity is doped in a semiconductor, a large number of holes are created. This does not make the semiconductor charged. But when holes diffuse from the p-side to the n-side in a p-n junction,the n-side gets positvely charged.Explain.

A carrom board (4ftxx4ft ) has the queen at the centre. The queen hit by the striker moves to the front edge, rebounds and goes in the hole behind the striking line. Find the magnitude of displacement of the queen a. from the centre to the front edge b. from the front edge to the hole and c. from the centre to the hole.
