Rotational Motion

\(I_1\) is the moment of inertia of a circular disc about an axis passing through its centre and perpendicular to the plane of disc. \(I_2\) is its moment of inertia about an axis \(A B\) perpendicular to plane and parallel to axis \(\mathrm{CM}\) at a distance \(\frac{2 R}{3}\) from centre. The ratio of \(I_1\) and \(I_2\) is \(x: 17\). The value of '\(x\)' is (R = radius of the disc)
