Homework Statement
Griffiths 3.36: Two straight wires having equal and opposite line charges are situated on either side of a conducting cylinder (all the wires and the cylinder are "long", so we can ignore edge effects--this is undergraduate electrostatics, after all!). The cylinder has no net charge and a radius R, the wires are an equal and opposite distance a > R apart from the cylinder's axis. Find the potential.
Homework Equations
Gauss' Law for the E-field (*much* easier than trying to calculate potential directly). Other than that, nothing really.
The Attempt at a Solution
I know this problem involves images; I'm just not sure where to place them (aside from inside the cylinder, obviously), and Griffiths is...less than helpful in figuring it out. If I did know where to put them, the problem would be easy, since all I'd need to do would be to put down the potential for a line charge and superposition the potentials from the two main charges and the images.
