JEE MainPhysicsRotational MotionMCQ+4 / −1
A thin circular ring of mass mmm and radius RRR is rotating about its axis with a constant angular velocity ω\omegaω. Two objects each of mass MMM are attached gently to the opposite ends of a diameter of the ring. The ring now rotates with an angular velocity ω′=\omega ' =ω′=
