- The equilibrium at x=2L is unstable; that is, if the proton is displaced leftward from point R, then F1 and F2 both increase but F2 increases more (because q2 is closer than q1), and a net
- force will drive the proton farther leftward. If the proton is displaced rightward, both F1 and F2 decrease but F2 decreases more, and a net force will then drive the proton farther rightward. In a stable equilibrium, if the proton is displaced slightly, it returns to the equilibrium position.
