1.

Two similar beads each of mass m slide smoothly along a uniform rod mass M and length l. the rod can rotate along an axis passing through its centre and normal to its length. Initially the rod is rotated with angular speed omega_(i) when beads are at centre C of the rod. The engular speed omega_(f) of the rod when beads slide to the two ends of the rod without any external force is given by (Momega_(i))/((xm+M)) where 'x' is
