9 9 9 9 - P cl 9 - I shall start with empty space and then add into that space one charge at a time until we have completely assembled the triangle of three charges. The legs of the right triangle have dimensions dX = 8.74e-02 meters and dy = 3.62e-02 meters. ' b . C12 q3 . Q1 The charges are as follows: . q1 = 1499-06 Coulombs. - (72 = 2.89eO6 Coulombs. . q3 = 6159-06 Coulombs. Determine the work required to place only ql into the position shown: :] Joules Determine the work required to ADD qg into the picture: :] Joules Determine the work required to ADD q3 into the picture: :] Joules Determine the total work required to complete all the above steps: :] Joules
