A uniform metal solid sphere is rotating with angular speed $\omega_0$ about diameter. If the temperature is raised by $50^{\circ} \mathrm{C}$. The angular speed will be [given $\alpha_{\text {metal }}=20 \times 10^{-5 \circ} \mathrm{C}^{-1}$ ]

$0.95 \omega_0$

$0.96 \omega_0$

$0.98 \omega_0$

$\omega_0$ (angular velocity is same)
