Rotational Motion

A solid sphere of mass \(500 \mathrm{~g}\) and radius \(5 \mathrm{~cm}\) is rotated about one of its diameter with angular speed of \(10 ~\mathrm{rad} ~\mathrm{s}^{-1}\). If the moment of inertia of the sphere about its tangent is \(x \times 10^{-2}\) times its angular momentum about the diameter. Then the value of \(x\) will be ___________.
