Two concentric conducting shells a and b are of radii R and 2R. A charge +q is centred at their center. Shell b is then earthed and a is given charge q. Find the charge on outer surfaces oboth shells.
Ans) THE charge on outer surface of A will be 2q and outer surface of B will be zero due to earthing charge on b will flow to earth.
