38. (a) We calculate the charged surface area of the cylindrical volume as follows: Arhr=+=+=220252πππ(0.20π(0.20m)(0.10 m)m)m. where we note from the figure that although the bottom is charged, the top is not. Therefore, the charge is q = σA= –0.50 µC on the exterior surface, and consequently (according to the assumptions in the problem) that same charge qis induced in the
