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.
