Assignment:
A charge of +10.7 micro-Coulombs is placed at the origin of a coordinate system. Another charge of -12.6 micro-Coulombs is placed at x = +0.19 m, y = +0.1 m. A third charge of +13.2 micro-Coulombs is placed at x = -0.19 m, y = 0 m. At what angle is the total electric filed is directed at the the point x = 0 m, y = +0.1 m if measured counter-clockwise from the positive x axis? Answer in degrees.
Provide complete and step by step solution for the question and show calculations and use formulas.
