A small copper spherical BB of radius a is located at the center of a larer hollow copper spherical shell of inner radius b and outer radius R. A charge of +q is on the small BB. The hollow copper shell has zero charge on it. a) What is the electric field within the BB (for radii r<a)? b) What is the electric field inside the copper shell (for radii that stisfy b<r<R) c) Draw a closed Gaussian surface within the copper of the shell. What is the total flux of the electric vector through this Gaussian surgace? This result implies that charge must lie on the inside surface of the spherical shell. What charge must reside on the inside surgface of the copper shell? Since the copper shell has a total charge of zero, what charge must reside on the outer surface of the copper shell? Please help me!!! :yuck: So far all I've been able to figure out is that the answer to b is 0 I think???
