  1. The moment of inertia of a disc of mass M and radius R about an axis, which is tangential to the circumference of the disc and parallel parallel to its diameter, is
    1. 3
      MR²
      2
    2. 2
      MR²
      3
    3. 5
      MR²
      4
    4. 4
      MR²
      5
Correct Option: C

Moment of inertia of disc about its diameter is

Id =
1
MR²
4


MI of disc about a tangent passing through rim and in the plane of disc is
I = Id + MR² =
1
MR² + MR² =
5
MR²
44
