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 potentialin the limit asV_{0}goes to zero?h

Express your answer in terms ofq,r, andε._{0}

2. Relevant equations

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!
