A thin smooth rod of length 
and mass 
is rotating freely with angular speed 
about an axis perpendicular to the rod and passing through its center. Two beads of mass 
and negligible size are at the center of the rod initially. The beads are free to slide along the rod. The angular speed of the system, when the beads reach the opposite ends of the rod, will be:
