Two rings of same radius and mass are placed suchthat their centres are at a common point and theirplanes are perpendicular to each other. The momentof inertia of the system about an axis passing throughthe ccntre and perpendicular to the plane of one of therings is (mass of the ring = m, radius = r)
  • a)
  • b)
    mr2
  • c)

  • d)
    2mr2
Correct answer is 'C'. Can you explain this answer?

The answer is a.
The moment of Inertia of such a system would be (3/2)MR^2.
The moment of Inertia of the system = The moment of Inertia of Ring rotating about an axis perpendicular to its plane + The moment of Inertia of Ring rotating about an axis in its own plane.
The moment of Inertia of Ring rotating about an axis perpendicular to its plane= MR^2
The moment of Inertia of Ring rotating about an axis in its own plane.= MR^2/2
So the moment of inertia of the system is (3/2)MR^2
