Chapter , Problem 50(choose chapter or problem)
Two positive point charges are on the axis at and A bead of mass and charge slides without friction along a taut thread that runs along the axis. Let be the position of the bead. (a) Show that for the bead experiences a linear restoring force (a force that is proportional to and directed toward the equilibrium position at and therefore undergoes simple harmonic motion. (b) Find the period of the motion.
