Determine the electrostatic potential energy of a system consisting of two charges `-2 muC` and `+4 muC` (with no external field) placed at (-8 cm, 0, 0) and (+8 cm, 0, 0) respectively, (b) Suppose the same system of charges is now placed in an external electric field. `E = A(1//r^2)`, where `A = 8 xx 105 cm^-2`, what would be the electrostatic potential energy of the configuration.
