2. A charge of -3.00 µC is fixed at the center of a compass. Two additional charges are fixed on the circle of the compass (radius = 0.1 m). The charges on the circle are -4.0 µC at the position due north and +5.0 µC at the position due east. What is the magnitude and direction of the net electrostatic force acting on the charge at the center? Specify the direction relative to due east.

Just how is anyone going to guess what the School Subject is with "umt?" Please look in the red margin to the left, up high, to pick a school subject someone might recognize. I only read your post out of curiosity but a teacher of the subject WILL read it, if the School Subject is recognizable.
