NEETPhysicsRotational Motion
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
Options
- ABoth (A) and (R) are true, and (R) is the correct explanation of (A)
- BBoth (A) and (R) are true, and (R) is not the correct explanation of (A)
- C(A) is true but (R) is wrong
- D(A) is wrong but (R) is true
Correct answer
C. (A) is true but (R) is wrong
Step-by-step solution
Moment of inertia I=M R^2 i.e., the moment of inertia depends on the mass of the body.
