Adopt a strategy of bringing in the charges one by one from infinity, and situate four electrons at the corners of a square 10.0 nm on a side. (a) Explain, using diagrams, the issue of attraction/repulsion & how the work performed in each step is affected by the sign(s) of the charge(s). (b) Calculate the total amount of work required to bring the charges to this arrangement. (c) Use U = 4TEO to determine the total potential energy of rij the system of four charges. (d) Comment on your finding in (c).(1) (e) Would your comment in (d) remain the same if, while keeping the two bottom-most charges the same, we replace the two topmost charges in the arrangement with two charges of the same magnitude, but different signs? You may use diagram(s) to illustrate your explanation.
