38. (a) We calculate the charged surface area of the cylindrical volume as follows: Ar h r =+ = + = 22 0 2 5 2 π π π(0.20 π(0.20 m)(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 = σ A = –0.50 µ C on the exterior surface, and consequently (according to the assumptions in the problem) that same charge q is induced in the
