A nonconducting sphere of radius R carries a uniform charge distribution of ρ C/m3. Obtain an expression for the total charge contained within a spherical region of radius r, concentric with the nonconducting sphere, for a) r < R; b) r ≥ R. Then use Gauss's law to find an expression for the electric field for r < R and r ≥ R. Make a sketch of the electric field as a function of r.
