The mass of a body cannot be considered to be concentrated at the centre of mass of the body for the purpose of computing its moment of inertia.
For then the moment of inertia of every body about an axis passing through its centre of mass would be zero.

Options

A. Statement I is True, Statement II is True, Statement ll is a correct explanation for Statement I.
B. Statement I is True, Statement II is True, Statement II is NOT a correct explanation for Statement I
C. Statement I is True, Statement II is False.
D. Statement I is False, Statement II is True.

Answer

A

Explanation

Moment of inertia is then sum of `mr^(2)` terms. We cannot change al the `r's`, keep m's the same and expected `Sigmam_(1)r_(i)^(2)` to remain unchanged.
