Figure shows two conducting thin concentric shells of radii r and 3r. The outer shell carries charge q and the inner shell is neutral. The amount of charge that flows from the inner shell to the earth after the key K is closed is equal to (1/n) th of the charge on the outer shell. What is the value of n?
