Conducting Spheres and Their Charge

  1. Feb 27, 2013 #1
    1. The problem statement, all variables and given/known data
    Suppose we have three identical conducting spheres and one of them carries a charge of Q. if they are lined up in a row and then separated one at a time without grounding them...
    a. only one will be charged with Q
    b. they will all be discharged
    c. one of them will have a charge of Q/2
    d. they will each have a charge of Q/3
    e. none of these

    2. Relevant equations



    3. The attempt at a solution
    my guess was d, but i dont really understand and grasp the question/concept. The answer is C. If someone could guide me in the right direction that would be great.

    Wait, I believe i got it. So when the 3 balls are together the charge Q spreads out as much as possible making the balls on either end Q/2 and the middle conductor with no charge. When one of the end balls is removed it keeps the charge of Q/2 and the process happens again with the other two balls. Is this right?
