A particle of mass m moves in a circular orbit


A particle of mass $m$ moves in a circular orbit

under the central potential field, $U(\mathrm{r})=\frac{-\mathrm{C}}{\mathrm{r}}$,

where $\mathrm{C}$ is a positive constant.

The correct radius - velocity graph of the particle's motion is :


Correct Option:




$|\mathrm{F}|=\frac{m v^{2}}{r}$


$\mathrm{v}^{2} \propto \frac{1}{\mathrm{r}}$
