» Rotational Motion » Moment of Inertia
Assertion (Ꭺ)
If two different axes are at same distance from the centre of mass of a rigid body, then moment of inertia of the given rigid body about both the axes will always be the same.
Reason (Ꭱ)
From parallel axis theorem, where all terms have usual meaning.
