The axis of the hole is at a distance b from the axis of the cylinder, where a<b<R (as shown in figure). The solid material of the cylinder has a uniform volume charge density ρ. Find the magnitude and direction of the electric field inside the hole, and show that this is uniform over the entire hole.
