PhysicsNEET 2021Moment of inertia, theorems of axes

System of Particles and Rotational Motion

From a circular ring of mass MM and radius RR an arc corresponding to a 90° sector is removed. The moment of inertia of the remaining part of the ring about an axis passing through the centre of the ring and perpendicular to the plane of the ring is KK times MR2MR^2. Then the value of KK is:

  1. A.34\dfrac34✓
  2. B.78\dfrac78
  3. C.14\dfrac14
  4. D.18\dfrac18

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
