A long horizontal rod has a bead which can slide along its length and  initially placed at a distance L from one end A of the rod. The rod is set in angular motion about A with constant angular  acceleration `alpha.` if the coefficient of friction between the rod and the bead is `mu`, and gravity is neglected, then the time after which the bead starts slipping is
