    1. The problem statement, all variables and given/known data
    Compute the electric potential energy for the charge configuration shown below.
    http://webct6.nic.bc.ca/webct/RelativeResourceManager/Template/CourseMaterials/CourseContent_2007FA/Assignments/PHY060W_Assignment_07_files/image025.jpg" [Broken]

    2. Relevant equations
    3. The attempt at a solution

    It is assumed that the charges are being brought in from infinity the -3.0 micro coulomb charge is charge one, 5.0 micro coulomb charge is number 3

    TPE= 0J+[(q1KQ2)/r2] + [(q1KQ3)/r1 + (q2KQ3)/r3]

    where q1 is charge 1, q2 and Q2 are charge 2, Q3 is charge 3, r1 is the distance between q1 and Q3, r2 is the distance between charge 1 and 2, r3 is the distance between q2 and Q3.

    am I on the right track can I simply solve this equation to get the right answer?
