Problem
Two identical positive point charges, each of magnitude +4.0μC, are fixed on the x-axis at x=−0.15m and x=+0.15m, respectively. A third point charge of magnitude −6.0μC is fixed on the y-axis at y=+0.20m. A +1.0μC test charge is placed at the origin.
(a) Calculate the x- and y-components of the electrostatic force exerted on the test charge by each of the three fixed charges. Show all work symbolically before substituting numerical values.
(b) Determine the magnitude and direction of the net force acting on the test charge. Express the direction as an angle measured counter-clockwise from the positive x-axis.
