A) \[\sqrt{\frac{\mu }{\alpha }}\]
B)
C) \[\frac{\mu }{\sqrt{\alpha }}\]
D) infinitesimal
Correct Answer: A
Solution :
Rod AB is set in angular motion about A, hence the radius of circular path of the bead is L. Its tangential acceleration is and therefore tangential force acting on the bead of mass m is = where a is the angular acceleration of the bead. Normal (or radial) force on the bead where is the angular velocity of the bead. The bead just starts slipping over the rod whenYou need to login to perform this action.
