## Homework Statement

A nonconducting sphere has radius R = 2.70 cm and uniformly distributed charge q = +7.00 fC. Take the electric potential at the sphere's center to be V0 = 0.

(a) What is V at radial distance r = 1.45 cm?

(b) What is V at radial distance r = R?

## Homework Equations

E = Vdv

V = k (q / r)

## The Attempt at a Solution

I was about to just integrate E from zero to r1 and then r2, but then I realized that as r increases, so does q so I can't just have a simple single integration. And then I didn't know what to do. Help? Thanks.
