Assertion : If we draw a circle around the centre of mass of a rigid body, then moment of inertia about all parallel axes passing through this circle has a constant value. Reason : Dimensions of radius of gyration are (\left[\mathrm{M}^{\mathrm{0}} \mathrm{L T}^{\mathrm{0}}\right]).

Options

  1. ABoth (A) and (R) are true and (R) is the correct explanation of (A).
  2. BBoth (A) and (R) are true and (R) is NOT the correct explanation of ((\mathrm{A})).
  3. C(A) is true but (R) is false.
  4. DBoth (A) and (R) are false.

Correct answer

B. Both (A) and (R) are true and (R) is NOT the correct explanation of ((\mathrm{A})).

Step-by-step solution

I=IC+mr2I=I_C+m r^2 Radius of gyration is a distance.
