A sphere with radius R has a charge density given by
ρ = cr3.
Use Gauss's law to find an expression for the magnitude of the electric field at a distance r from the center of the sphere, where we have the following. (Use the following as necessary: c, r, R, and ε0. Assume c is positive.)
(a)
r < R
E =
(b)
r > R
E =
