Three charges are located at the corners of a rectangle as follows:
Charge A: lower left corner, -3.0 Î¼C
Charge B: upper left corner, -6.1 Î¼C
Charge C: upper right corner, +2.7 Î¼C
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?
