A solid metal sphere of radius r is inside a metal concentric spherical shell of inner radius 2r and outer radius 3r. A charge is place on the
solid metal sphere and it is found that the potential at its surface is V1 (at r) and that the potential at the outer surface of the spherical
shell is Va (at 3r). In terms of V1 and V3, what is the potential at the inner surface of the metal shell (at 2r)?
A. 3V1/2 B. V3 C. V1 D. 2V3/2
