A uniform solid sphere is rotating with angular speed of $\omega_0$ about a diameter . The temperature of the solid is suddenly increased by $100^{\circ}$. What will be the new angular speed. $(\alpha = 3 \times 10^{-4}\;per ^{\circ}c)$

Question

$\begin{array}{1 1} 1.101 \omega_0 \\ 0.986\;w_0 \\ 0.862\;\omega_0 \\ 0.904\omega_0 \end{array}$
