Answered & Verified by Expert
Two stones of masses $\mathrm{m}$ and $3 \mathrm{~m}$ are whirled in horizontal circles, the heavier one in radius $\left(\frac{\mathrm{r}}{3}\right)$ and lighter one in radius ' $\mathrm{r}^{\prime}$. The tangential speed of lighter stone is 'n' times that of the value of heavier stone, when they experience same centripetal force. The value of $\mathrm{n}$ is

The correct answer is:
3
Centripetal force $=\frac{\mathrm{mV}_{1}^{2}}{\mathrm{r}}=\frac{3 \mathrm{mV}_{2}^{2}}{\left(\frac{\mathrm{r}}{3}\right)}$
$\begin{aligned} \frac{\mathrm{V}_{1}^{2}}{\mathrm{~V}_{2}^{2}} &=9 \\ \frac{\mathrm{V}_{1}^{2}}{\mathrm{~V}_{2}^{2}} &=3 \end{aligned}$
$\begin{aligned} \frac{\mathrm{V}_{1}^{2}}{\mathrm{~V}_{2}^{2}} &=9 \\ \frac{\mathrm{V}_{1}^{2}}{\mathrm{~V}_{2}^{2}} &=3 \end{aligned}$
