## Homework Statement

A point charge q is located in the xy plane near two grounded conducting planes intersecting at right angles as shown in the Figure. The z axis lies along the line of intersection of the planes. Find and justify (mathematically show) the force acting on this charge q (both direction and magnitude should be specified).

1. Think about how much charge would be induced on the conducting planes.

2. What would be the potential on the conducting planes (This is the boundary condition) and what can you do to maintain such a condition?

3. If a different method was used for your calculation, please describe the method.

A .doc file containing the question and a diagram is attached.

## The Attempt at a Solution

I'm assuming a negative charge is induced on the conducting planes, but beyond that I seriously have no clue. Absolutely any help whatsoever would be greatly appreciated.

I found a website with a related problem by google searching "force point charge conducting plane." It's the davidpace one ( I can't link to websites yet). Can I do basically the same thing with each conducting plane individually and use vector addition to find the resultant force?
