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

1.	A long horizontal rod has a bead which can slide along its length and is initially placed at a distance L from one end A of the rod. The rod is set in angular motion about A with a constant angular acceleration, alpha. If the coefficient of friction between the rod and bead is mu, and gravity is neglected, then the time after which the bead starts slipping is :
Answer» `SQRT((MU)/(ALPHA))` `(mu)/(sqrt(alpha))` `(1)/(sqrt(mu alpha))` infinitesimal Answer :d
