Rotational Motion question

2022 · 26 Jun · Shift 1 · Q46

JEE MainPhysicsRotational MotionMCQ+4 / −1
A thin circular ring of mass M and radius R is rotating with a constant angular velocity 2 rads −-− 1 in a horizontal plane about an axis vertical to its plane and passing through the center of the ring. If two objects each of mass m be attached gently to the opposite ends of a diameter of ring, the ring will then rotate with an angular velocity (in rads −-− 1).
  1. A
    M(M+m){M \over {(M + m)}}(M+m)M​
  2. B
    (M+2m)2M{{(M + 2m)} \over {2M}}2M(M+2m)​
  3. C
    2M(M+2m){{2M} \over {(M + 2m)}}(M+2m)2M​
  4. D
    2(M+2m)M{{2(M + 2m)} \over M}M2(M+2m)​
