Homework Statement
A nonconducting solid sphere of radius R has a volume charge density that is proportional to the distance from the center. That is rho=Ar for r is less than/equal to , A is a constant. Find the total charge on the sphere.
Homework Equations
The Attempt at a Solution
rho=Ar=Q/V
Q=Ar(4/3)*pi*R^3
Is that it?
