1. The problem statement, all variables and given/known data A conducting spherical shell of inner radius b and outer radius c is concentric with a small metal sphere of radius a<b. The metal sphere has a positive charge Q while the total charge on the conducting spherical shell is -Q. Assume the potential is 0 very far from all charges. a. What is the electric potential of the metal spherical shell? b. what is the electric potential of the metal sphere? I'm a little confused about what they're asking from the questions. for (a) am i supposed to make 3 electric potential equations at a<r<b, b<r<c, and r>c? and for just r>a for part b?
