A very long, solid insulating cylinder with radius R has a  cylindrical hole with radius a bored along its entire length. The axis of the hole is at a distance  b from the axis of the cylinder, where `altbltR` (as shown in figure). The solid material of the cylinder has a uniform volume charge density `rho`. Find the magnitude and direction of the electric field inside the hole, and show that this is uniform over the entire hole.   img src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/BMS_V03_C02_E01_032_Q01.png" width="80%"
