Homework Statement
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?

Ah for the second problem, it ended up as x = R / sqrt(2)
x = 2.41 cm / sqrt(2) = 1.7041 cm
As for the first: http://img515.imageshack.us/img515/4338/netfieldzero3ir5.gif
So I suppose a net field of zero can't be between them. That...
