Expressing the interaction energy between two spheres?

  1. Oct 17, 2013 #1
    1. The problem statement, all variables and given/known data
    Two identical spheres with radius R have uniform charge Q throughout their volume and separated d>2R apart


    2. Relevant equations
    https://www.physicsforums.com/attachment.php?attachmentid=63061&d=1382054852 is the general potential energy equation

    attachment.gif this should be my total charge inside a sphere?

    attachment.gif This is the equation for the interaction energy

    3. The attempt at a solution
    I found the total charge of the sphere (2nd Eqn.) and I believe that to find the interaction energy, I should treat that as [itex]\Phi[/itex]1 and then use the charge from sphere 2?
