A charge of +10nC is uniformly distributed on a thin sphericalshell of radius 12.0cm. (Assume the potential is zero very far fromall chargers.)
a) What is the magnitude of the electric field just outside andjust inside the shell?
b) What is the magnitude of the electric potential just outside andjust inside the shell?
c) What is the electric potential at the center of the shell?
d) What is the magnitude of the electric field at the center of theshell?
