Suppose that the charge density of the spherical charge distribution shown in the figures below is ρ(r) = ρ0r/R for r ≤ R and zero for r > R. Obtain expressions for the electric field both inside and outside the distribution. (Use any variable or symbol stated above along with the following as necessary: ε0.) (a) (b) inside E→ = r^ outside E→ = r^
