3. A long insulating cylinder with radius R (and length >> R) has nonuniform charge density given by the equation p = A., where A is a constant and r is the distance from the central axis of the cylinder . (The charge density is zero outside of the cylinder). Find an equation for the magnitude of the radial electric field both inside and outside of the cylinder in terms of the distance from the cylinder's central axis, D. (Assume we are far from the ends of the cylinder). Please do an O&P, Solve, and Reflect.
