1. The problem statement, all variables and given/known data A nonconducting sphere has radius R = 3.71 cm and uniformly distributed charge q = +3.76 fC. Take the electric potential at the sphere's center to be V0 = 0. What is V in volts at radial distance (a) r = 1.00 cm and (b) r = R? 2. Relevant equations I suppose: Electric field of spherical shell = ( 1 / (4 x pi x E) ) * ( q / r² ) 3. The attempt at a solution Completely stuck, don't even know where to begin > <.
