A small charge of +1.0 micro-Coulomb (µC) is constrained to move (frictionlessly) along the x-axis. There is also a charge of +1.0 µC fixed at x = 0, and another charge of +2.0 µC fixed at x = 1.0 m, both fixed charges also on the x-axis. (a) Where is the equilibrium position of the movable charge? (b) Is the equilibrium stable or unstable? Explain.

A particle is constrained to move along the positive x-axis under the influence of a force whose potential energy is U(x) = U_0(2 cos x/a - x/a) where U_0 and a are positive constants. Plot U versus x. A simple hand sketch is fine. Find the equilibrium point(s). For each equilibrium point, determine whether the equilibrium is stable or unstable.
