PHYS208 Fundamentals of Physics II

Hint for Ch. 26, special problem #2

Consider one conductor to have linear charge density of +lambda and the other conductor to have -lambda. Employ the superposition theorem to consider the contribution of each line of charge to the total E; the contribution from each can be found using the typical configuration of a gaussian cylinder. (See Group Exercise #2.)

Evaluate the resulting potential difference between the two conductors by evaluating the line integral relating E to V, and from that a formula for capacitance.
