I have to find the electric field everywhere using Gauss’ law in differential form. Charge density is [tex]\rho = \rho_{0}r^{3}[/tex] for a<r<b and 0 otherwise in spherical symmetry and then in cylindrical coordinates(adsbygoogle = window.adsbygoogle || []).push({});

[tex] \nabla \cdot D=\rho [/tex]

I have look for D and then just get E = D/epsilon. D is where I need help. Thanks
