PHYS208 Fundamentals of Physics II

Hint for Ch. 26, special problem #1

Consider the inner conductor to have linear charge density of +lambda and the outer conductor to have -lambda. Evaluate the E using a gaussian surface between the two conductors, and then evaluate the resulting potential difference between the two conductors. Substitute the parameters stated in the problem into the resulting formula for capacitance.

(HRW derives a formula for the capacitance.)
