Statement-1: if moment of inertia of a r...

Statement-1: if moment of inertia of a rigid body is equal about two axis, then both the axis must be parallel.
Statement-2 from parallel axis theorem `I=I_(cm)+md^(2)`, where all terms have usual meaning.

A

Statement-1 is true, Statement-2: is true, Statement-2 is a correct explanation for Statement-1.

B

Statement-1 is true, Statement-2: is true, Statement-2 is NOT a correct explanation for Statement-1.

C

Statement-1 is true but statement-2 is false

D

Both statement 1 false and statement 2 are true.

Text Solution

Verified by Experts

The correct Answer is:
D

For a uniform solid sphere moment of inertia about any axis passing through centre is same. All this axis are not parallel. Hence Statement-1 is false, Statement-2 is True.
