 Now we have a solid non conductive sphere of radius **r0** uniformly charged surrounded by a spherical conductive shell of inner and outer radius **r1,r2**. The density of charge in the non-conductor is $\rho_E$. Now we have a solid non conductive sphere of radius **r0** uniformly charged surrounded by a spherical conductive shell of inner and outer radius **r1,r2**. The density of charge in the non-conductor is $\rho_E$.
 To solve the E field inside the non-conductive sphere we apply Gauss' law to a spherical surface of radius r<r0. To solve the E field inside the non-conductive sphere we apply Gauss' law to a spherical surface of radius r<r0.
-  * a) $E*4\pi\r^2=\frac{\rho *4/3 \pi r^3}{\epsilon_0}$. Therefore $E=\frac{\rho r}{3\epsilon_0}$.+  * a) $E*4\pi r^2=\frac{\rho *4/3 \pi r^3}{\epsilon_0}$. Therefore $E=\frac{\rho r}{3\epsilon_0}$.
