An infinitely ong insulating cylinder of radius r1 has a charge uniformly spread throughout its volume so that the charge per unit volume is p. It is inside a conducting cylinder with inner radius r1 and outter radius r2. Find the difference in the electric potential between a point on the axis, at the center of the cylinder, and a point a distance 2r2 from the axis of the cylinder
