A thin smooth rod of length L and mass M is
rotating freely with angular speed ₀ about an
axis perpendicular to the rod and passing
through its center. Two beads of mass m 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 :-
