Assertion : The moment of inertia of a r...

Assertion : The moment of inertia of a rigid body reduces to its minimum value, when the axis of rotation passes through its centre of gravity.
Reason : The weight of a rigid body always acts through its centre of gravity.

A

If both, Assertion and Reason are true and the Reason is the correct explanation of the Assertion.

B

If both, Assertion and Reason are true but Reason is not a correct explanation of the Assertion.

C

If Assertion is true but the Reason is false.

D

If both, Assertion and Reason are false.

Text Solution

Verified by Experts

The correct Answer is:
A
Both, the assertion and reason are true and the latter is correct explanational of the former. This follows from the theorem of parallel axes on moment of inertia.
