A hollow metallic sphere is charged. Insider the sphere

A small sphere of radius a carrying a positive charge q, is placed concentrically inside a larger hollowconducting sheli of radius b (bgt a). This outer shell has charge Q on it. Show that if these spheres are connected by a conducting wire, charge will always flow from the inner sphere to the outer sphuisirrespective of the magnitude of the two charges.

Inside a charged thin conducting shell of radius R, a point charge +Q is placed as shown in figure potential of shell may be

A solid conducting sphere of radius R is surrounded by a concentric metallic shell of inner radius 2R and outer radius 3R. The shell is earthed. The inner sphere is connected to a switch S by a thin conducting wire through a small hole in the shell. By closing the switch S, the inner sphere is connected to a distant conducting sphere of radius R having charge Q. Find the charge that flows to earth through wire AB.
