A charge having -3.00 µC is fixed at the center of the compass. The two additional charges are fixed on the circle of the compass having radius 0.135 m. The charges on the circle are -4.50 µC at the position due north and +5.00 µC at the position due east. Determine the magnitude and direction of the total electrostatic force acting on the charge at the center? State the direction relative to due east (in the direction of right) (0°)
