Problem
Three point charges are fixed at the corners of a right triangle in the xy-plane: +3.0μC at (0,0), −3.0μC at (0.40m,0), and +3.0μC at (0,0.40m). Without performing detailed numerical calculations, determine whether the total electric potential energy of the three-charge system is positive, negative, or zero. Briefly justify your answer.
