A charge of -2.85 C is fixed at the center of a compass. Two additional charges are fixed on the circle of the compass,
which has a radius of 0.108 m. The charges on the circle are -4.3 pc at the position due north and +5.40 pc at the position
due east. What are the magnitude and direction of the net electrostatic force acting on the charge at the center? Specify the
direction relative to due east.
