There are two concentric spherical shell of radii r and `2r`. Initially, a charge Q is given to the inner shell and both the switches are open.

If switch `S_1` is closed and then opened, charge on the outer shell will be

There are two concentration conducting spherical shells of radii r and 2r initially a charge Q is given to the inner shell Now, switch S_(1) is closed and opened then S_(2) is closed and opened and the process is repeated n times for both the keys alternatively. Find the final potential difference between the shells. [(1)/(2^(n+1))[(Q)/(4pivarepsilon_(0))r]]

There are two concentric spherical shells of ratii r and 2r. Intially a charge Q is given to the inner shell. Now switch S_(1) is closed and S_(2) is opned and the process is repeated n times for both the keys altermatively. Find the final potential between the shells.
