Unformatted text preview: Coulomb’s Law. The magnitude of the force is given by Coulomb’s Law: 1 2 2 12 12 2 F   K  q  q  3 Kq x = F = = Since the force is nonzero and repulsive, the charges will accelerate in the directions specified by the forces. Can we add a third charge to counteract this force and leave all charge stationary? Yes! Place a third positive charge between charges 1 and 2. Note that the superposition principle holds: adding a third charge does not affect the force between charges 1 and 2. Let particle 1 reside at x = 0, particle 2 at x = 1 m, and particle 3 at x = r , where 0 < r < 1....
