Physics - Gravitation Question with Solution | TestHub

A satellite describes an elliptic orbit about a planet. Denoting by ${\mathrm{r}}_0$ and ${\mathrm{r}}_1$, the distances corresponding to the perigee and apogee of the orbit. The radius of curvature of the orbit at point A and B in terms of ${\mathrm{r}}_0$ and ${\mathrm{r}}_1$ is $\frac{\alpha {\mathrm{r}}_0{\mathrm{r}}_1}{3\left({\mathrm{r}}_0+{\mathrm{r}}_1\right)}$. The value of $\alpha$ is :-
