Equal charges +q are situated in a circle with radius R, and they are equally spaced as shown in Figure 1 below. +4 +9 +9 R +9 +9 +9 Figure 1: Equal charges +q are situated in a circle a. What is the force (magnitude and direction) on a charge +Q at the center of thecirele"? We remove only the +q charge which we is located at "3-o'clock." b. What now is the force (magnitude and direction) on the charge +Q at the center ofthe circle?
