The strategy to use when calculating the force exerted by a set of several point charges is to find first the forces exerted by each of the point charges individually. The force exerted by the entire set of charge is the net force resulting from the forces exerted by the individual charges. The forces from the individual charges in this problem are shown in the diagram below. F12 191 0.100 m FR F13 93 0.316 m so the magnitude of this repulsive force is given by the following equation %3D The charge q, exerts a repulsive force F, 2 on q, as shown in the diagram. The distance separating these charges is r,2 where k, is the Coulomb constant in SI units. e 19,|1921 F12 = k r12 c2) х 10-18 (8.99 x 109 N · m²/c2)- ? m)* x 10-6 N
