Solution

Q.
Moment of inertia of a disc of mass $M$ and radius 'R' about any of its diameter is $\frac{M R^{2}}{4}$ . The moment of inertia of this disc about an axis normal to the disc and passing through a point on its edge will be, $\frac{x}{2} M R^{2}$ . The value of $x$ is __________ . [2023]

Ans.
(3)

$I = I_{c m} + M d^{2}$

$= \frac{M R^{2}}{2} + M R^{2} = \frac{3}{2} M R^{2}$

$\Rightarrow x = 3$
