Q2.

A disc has mass 'M' and radius 'R'. The axis of rotation passes through a point P in the plane of the disc, which is at a distance 'x' $(x \lt R)$ from the center of the disc and perpendicular to the plane of the disc. M.I. of disc about the axis of rotation is found to be $MR^2$. The value of 'x' is

(A)

$2R$

(B)

$\sqrt{2}\ R$

(C)

$\dfrac{R}{\sqrt{2}}$

(D)

$\dfrac{R}{2}$
