A solid conducting sphere of radius `10 cm` is enclosed by a thin metallic shell of radius `20 cm`. A charge `q = 20 mu C` is given to the inner sphere is connected to the shell by a conducting wire.

A solid conducting spere of radius 10 cm is enclosed by a thin metallic sheel of radius 20 cm . A charge q=20 mu C is given to the inner spere. Find the heat generated in the process. The inner sphere is connected to the shell by a conducting wire. .

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.

A solid conducting sphere of radius a is enclosed in a concentric shell of radius b gt a . The charge on the inner sphere is 3muC and on the conducting shell is -10muC . The potential difference between the conductors is V. If +10muC additional charge is given to the outer shell, the new potential difference is

Figure shows a solid conducting sphere of radius 1 m. enclosed by a metallic shell of radius 3 m such that their centress coincide. If outer shell is given a charge of 6 mu C and inner sphere is earthed, find megnitude charge on the surface of inner shell
