Electrostatic question

  1. Feb 8, 2005 #1
    I have just started electricity in physics and am wondering how to do this homework questions.

    The question is:

    Sphere A and B are insulated metal spheres with charges of +10 micro C and -5 micro C respectively. If sphere A has twice the radius of sphere B, what will be the charge on each sphere after they are touched together and then separated.

    HINT:When being put in contact (and afterwards as well) the two spheres must have the same electric potential.
