Question
A nonconducting sphere has a radius
R = 2.31 cm and uniformly distributed
charge q = +3.50 fC. Take the electric
potential at the sphere’s center to be V = 0.
What is V at a radial distance (a) r = 1.45
cm and (b) r = R. (HINT: Use Gauss’ law
9
to find an expression for the electric field of
a sphere, then use the line integral
