Rotational Motion

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, \(\frac{x}{2}\) MR\(^{2}\). The value of \(x\) is ___________.
