Three charges are located at the corners of a rectangle as follows:
Charge A: lower left corner, -3.0 μC
Charge B: upper left corner, -6.1 μC
Charge C: upper right corner, +2.7 μC
The distance between A and B is 0.16 m and between B and C it is 0.25 m.
How much work must an external force acting on the particles (like, your hands) do in order to move the charges infinitely far from each other?

    The energy to do this will be equal to the PE the system has:
    PE=k(Q1*Q2)/d12 +k(Q1Q3)/d13 +kQ2Q3/d23

    And what is neat, you do this by moving only two charges, that puts all three infinitely apart.
