Rotational Motion question

2019 · 9 Apr · Shift 2 · Q43

JEE MainPhysicsRotational MotionMCQ+4 / −1
A thin smooth rod of length L and mass M is rotating freely with angular speed ω\omegaω 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 :-
