The moment of inertia of a then circular disc about an axis passing through its centre and perpendicular to its plane is `I`. Then, the moment of inertia of the disc about an axis parallel to its diameter and touching the edge of the rim is

Text Solution

Verified by Experts

`I=(MR^(2))/2rArrMR^(2)=2I`
`M.I.` of the disc about tangent in a plane
`=5/4MR^(2)=5/2 I`
