Problem 4: A metal sphere of radius 0.19 m carries an electric charge of +0.41 µC, which is spread uniformly over the sphere's
surface. The sphere is fixed, by means of insulating supports, at the center of a larger metal shell, with inner radius 0.67 m and outer radius 4.55
m. Now a charge of -0.41 µC is placed on the metal shell and distributes itself uniformly over the shell's inner surface.
Part (a) What is the potential on the outer surface of the spherical shell, in megavolts? You can assume the potential is zero at infinity.
Vahell =
Part (b) What is the potential on the surface of the sphere, in megavolts?
