Two charges touching each other

    Hey!
    This isn't a question from a book. Its something that I am not 100% sure about.

    The question
    What happens if two iron balls with charge Q each, touch each other?

    My thought
    These balls can be seen as a separate ball with a charge of 2Q. ( I am not so sure what to say about the volume of that iron ball though)

    Two iron balls of the same size? What does symmetry say?

    Lets say that they are identical spheres.

    I wrote my thoughts above. :) Or do you mean the volume? The volume will be 2*the volume of one metall ball. The charge/cm^3 must be the same I guess.
