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)

The moment of inetia of a rod about an axis passing through its centre and perpendicular to its length is $\frac{1}{12} M L^2$, where $M$ is the mass and $L$ is the length of the rod. The rod is bent in the middle, so that the two halves make an angle of $60^{\circ}$. The moment of inertia of the bent rod about the same axis would be

$\frac{1}{48} M L^2$

$\frac{1}{12} M L^2$

$\frac{1}{24} M L^2$

$\frac{1}{8 \sqrt{3}} M L^2$
