A conducting sphere (radius a) carries a charge Q. The sphere is surrounded by a linear dielectric out to a radius of b. A) find the electric field everywhere B) find the potential V at the center of the sphere, relative to r = infinity C) what effect does the dielectric have on the field outside the sphere? Explain
