Physics - Circular Motion Question with Solution | TestHub

ABCD is a smooth horizontal fixed plane on which mass ${\mathrm{m}}_1=0.1\mathrm{kg}$ is moving in a circular path of radius $\mathrm{r}=1\mathrm{m}$. It is connected by an ideal string which is passing through a smooth hole and connects to mass ${\mathrm{m}}_2=$ $\frac{1}{\sqrt{2}}\mathrm{kg}$ at the other end as shown. ${\mathrm{m}}_2$ also moves in a horizontal circle of same radius of 1m with a speed of $\sqrt{10}\mathrm{m}/\mathrm{s}$. If $\mathrm{g}=10\mathrm{m}/{\mathrm{s}}^2$ then the speed of ${\mathrm{m}}_1$ is :-\\ (A) $\sqrt{10}\mathrm{m}/\mathrm{s}$\\ (B) 10 m/s\\ (C) $\frac{1}{\sqrt{10}}\mathrm{m}/\mathrm{s}$\\ (D) None of these\\
