Question:medium
A solid sphere of mass \(M\) and radius \(R\) is split into two pieces of masses \( \frac{7M{8} \) and \( \frac{M}{8} \). The piece of mass \( \frac{7M}{8} \) is converted into a disc of radius \(2R\) and thickness \(t\) whose moment of inertia is \(I_1\). The other piece is made into a solid sphere with moment of inertia \(I_2\). Find \( \frac{I_1}{I_2} \).}
