A point charge of +10 micro-coulombs lies at x = -0.39 m, y = 0 m, a point charge of -5.7 micro-coulombs lies at x = +0.39 m, y = 0 m, and a point charge of +14.9 micro-coulombs lies at x = 0 m, y = -0.3 m. A point charge of +10 micro-coulombs is moves from x = 0 m, y = +0.11 m to x = 0 m, y = +0.54 m. How much does the kinetic energy of the charge which is moved change in Joules?
