Consider two concentric spherical metal shells of radii ‘a’ and b>a .The outer shell has charge Q but the inner shell has no charge.Now the inner shell is grounded ,This means that the inner shell will come at zero potential and that electric fields lines leave the outer shell and end on the inner shell.(a) Find the charge on the inner shell Find the potential on outer sphere.

and ii.) find the potential of the inner shell. Consider two concentric spherical metal shells of radii 'a' and b>a .The outer shell has charge Q but the inner shell has no charge.Now the inner shell is grounded if the inner shell has charge +q0 and the outer shell is earthed In (Fig. 3.73) then i.) determine the charge on the outer shell
