Physics 417G : Solutions for Problem set 3
... e) Find the resulting potential inside and outside the sphere. Hint: It is important to have finite potentials both inside and outside. This will determine possible expansions inside and outside. This allows us to determine Bl in terms of Al . The surface charge provides a discontinuity on the radia ...
