Shown below is a configuration of charges that has been formed into a right triangle. We shall consider the process of the work required to assemble this collection of charges in the manner shown. To do so, we 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 = 6.8e-02 meters and dy = 1.38e-02 meters. dy 9₁ The charges are as follows: • 91 = -7.64e-06 Coulombs. 92 2.21e-06 Coulombs. = ● 92 ● 93 = -5.2e-06 Coulombs. d₁ Determine the work required to place only q1 into the position shown: Determine the work required to ADD 92 into the picture: Determine the work required to ADD 93 into the picture: Determine the total work required to complete all the above steps: Joules Joules 93 Joules Joules
