PhysicsEasysingle choice

The figure shows a body of arbitrary shape. $O$ is the centre of mass of the body and mass of the body is $M$ . If $I_{C C^{'}} = I_{0}$ then $I_{A A^{'}}$ will be equal to

Options:

Answer:

Solution:

Let $B B^{'}$ be an axis passing through centre of mass and parallel to $C C^{'}$ .

$∴ I_{A A^{'}} = I_{B B^{'}} + 4 M d^{2}$

$= I_{C C^{'}} - M d^{2} + 4 M d^{2}$

$I_{A A^{'}} = I_{C C^{'}} + 3 M d^{2}$
