A charge of -3.00 µC is fixed at the center of a compass. Twoadditional charges are fixed on the circle of the compass (radius =0.100 m). The charges on the circleare -3.90 µC at the position duenorth and +5.00 µC at the position due east. What is the magnitude and direction of the net electro static force acting on the charge at the center? Specify the direction relative to dueeast (0°).
