Assertion (A) The moment of inertia of a steel sphere is larger than the moment of inertia of a wooden sphere of same radius.
Reason (R) Moment of inertia is independent of mass of the body.
The correct one is
Both $(A)$ and $(R)$ are true, and $(R)$ is the correct explanation of (A)
Both $(A)$ and $(R)$ are true, and $(R)$ is not the correct explanation of (A)
(A) is true but (R) is wrong
(A) is wrong but (R) is true
Solution
Moment of inertia
$I=M R^2$
i.e., the moment of inertia depends on the mass of the body.
