Homework Help: Induced charge on plates of capacitor

  1. Mar 4, 2010 #1
    1. The problem statement, all variables and given/known data


    Two large plane conducting plates are connected by a wire and are a distance D apart in a vacuum. A point charge +q is placed in the space between them, and at a distance b(<D) from one of them. What proportion of charge q is induced in each plate?

    2. Relevant equations



    3. The attempt at a solution

    I was wondering if perhaps the charge induced gets split in proprtion to the distances; that is one plate would have (b*q)/D and the other would have (D-b)*q/D in terms of charge proportions, but there must be something more to it. I considered maybe replacing the charge with an infinite plate of charge +q, a distance b from one of the plates, and then considering the field produced, but I am not sure.

    As always, any instruction and I would be grateful.
