A hollow, thin-walled insulating cylinder of radius R and length L (like the cardboard tube in a roll of toilet paper) has charge Q uniformly distributed over its surface. Part A Calculate the electric potential at any point x along the axis of the tube. Take the origin to be at the center of the tube, and take the potential to be zero at infinity. Express your answer in terms of the given quantities and appropriate constants. Part B Use the result of part A to find the electric field at any point x along the axis of the tube. Express your answer in terms of the given quantities and appropriate constants.
