Electric Flux and Gauss's Law for Non-Uniform Charge Density in a Solid Cylinder

[johafmorsha]

Problem
A long non conducting solid cylinder of radius R has a non-uniform change density rho or (p) that is a function of the radical distance r from the axis of the cylinder. given by rho or p(r)=Ar^2 Find the E-field at regions r<R and r>R?

Ah Gauss's Law, this brings meback...

Draw a picture.
