A bead can slide on a smooth straight wire and a particle of mass `m` attached to the bead by a light string of length `L`. The particle is held in contact with the wire and with the string taut and is then let fall. If the bead has mass `2m` then when the string makes an angle `theta` with the wire, the bead will have slipped a distance.
