A charge of -6.5 micro-Coulombs is placed at the origin of a coordinate system. Another charge of -7.6 micro-Coulombs is placed at x = +0.29 m, y = +0.17 m. A third charge of +14 micro-Coulombs is placed at x = -0.29 m, y = 0 m. What is the magnitude of the total electric field on the charge at the the point x = 0 m, y = +0.17 m in units of 1 x 106 N/C?
