Question

$\mathrm{v}_{0}=\sqrt{\frac{\mathrm{GM}}{\mathrm{r}}} \Rightarrow \mathrm{v}_{0} \propto \frac{1}{\sqrt{\mathrm{r}}}$

$\Rightarrow \frac{\mathrm{v}

Vedclass · Accepted Answer

$\frac{v}{2}$

Vedclass · Answer

$\mathrm{v}_{0}=\sqrt{\frac{\mathrm{GM}}{\mathrm{r}}} \Rightarrow \mathrm{v}_{0} \propto \frac{1}{\sqrt{\mathrm{r}}}$

$\Rightarrow \frac{\mathrm{v}_{1}}{\mathrm{v}_{2}}=\sqrt{\frac{\mathrm{r}_{2}}{\mathrm{r}_{1}}} \Rightarrow \quad \frac{\mathrm{v}}{\mathrm{v}_{2}}=\sqrt{\frac{4 \mathrm{R}}{\mathrm{R}}} ; \mathrm{v}_{2}=\frac{\mathrm{v}}{2}$
