There is an equilateral triangle with sides of 9 meters. There are charges on each point of the triangle and no other nearby charges. The three charges are -60 microcoulombs, -81 microcoulombs, and 26 microcoulombs. What is the potential energy of this arrangement of charges in Joules? Zero potential energy is the charges infinitely far from each other.
