When the temperature of a body increases from t to \((t+\Delta t)\), its moment of inertia increases from \(\text { I }\) to \((I+\Delta I)\) about the same axis. The coefficient of linear expansion of the body is \(\text { II }\). The ratio of \(\frac{\Delta I}{I}\) is equal to
- \(\frac{\Delta t}{t}\)
- \(\frac{2 \Delta t}{t}\)
- \(\text { x } \Delta t\)
- \(\text { ZI Δt }\)
Answer
(D) ZI Δt
