Question

A charge of -5 micro-coulombs is placed at the origin, a charge of +3 micro-coulombs is placed at x = - 41 cm, y = 0 m, and a charge of -9 micro-coulombs is placed at x = 0, y = +20 cm. A fourth charge of -6 micro-coulombs moves from x = +17 cm, y = 0 m to x = -20 cm, 0 m. What is the change in electric potential energy, in Joules, of the fourth charge as it moves from the initial to the final point?
