    Do you know the relation between work and electric potential energy?
  6. Mar 26, 2013 #5
    Work = the change in electric potential energy? Is that what you are refering to?
  7. Mar 26, 2013 #6
    Can you work out the potential energy for the 2 configurations?
  8. Mar 26, 2013 #7
    yes I have

    kq1q2/0.6^2 Epi
    kq1q2/0.4^2 Epf

    then what should I do

    This is the electric force, not the potential energy.
    The PE varies as 1/r, not 1/r2

    Also, there are 2 fixed charges - you've only accounted for 1 of them.
