1. The problem statement, all variables and given/known data A hollow cylinder of radius r and height h has a total charge q uniformly distributed over its surface. The axis of the cylinder coincides with the z axis, and the cylinder is centered at the origin, as shown in the figure. What is the potential V0 in the limit as h goes to zero? Express your answer in terms of q, r, and ε0. 2. Relevant equations http://photo.ringo.com/240/240690564O546905961.jpg [Broken] 3. The attempt at a solution with h=0, the values under the root would be 1 (1+0), and the other values in the parenthesis would be zero, so we would have ln(1) which is 0, and then 0 multiplied times the rest would also be 0, but this is incorrect. Thanks in advance for the help!
