Three charges are fixed to an x, y coordinate system. A charge of+14 µC is on the y axis aty = +3.0 m. A charge of -14µC is at the origin. Finally, a charge of +45 µC is on the x axis at x =+3.0 m. Decide the magnitude and direction of the net electrostatic force on the charge at x = +3.0 m. Identify the direction relative to the -x axis.
