Assertion (A) The moment of inertia of a steel sphere is larger...

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

  1. ABoth (A)(A) and (R)(R) are true, and (R)(R) is the correct explanation of (A)
  2. BBoth (A)(A) and (R)(R) are true, and (R)(R) is not the correct explanation of (A)
  3. C(A) is true but (R) is wrong
  4. 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=MR2I=M R^2 i.e., the moment of inertia depends on the mass of the body.
