Physics - Gravitation Question with Solution | TestHub

Two satellites A and B of masses ${\mathrm{m}}_1$ and ${\mathrm{m}}_2\left({\mathrm{m}}_1=2{\mathrm{m}}_2\right)$ are moving in circular orbits of radii ${\mathrm{r}}_1$ and ${\mathrm{r}}_2\left({\mathrm{r}}_1=4{\mathrm{r}}_2\right)$, respectively, around the earth. If their periods are ${\mathrm{T}}_{\mathrm{A}}$ and ${\mathrm{T}}_{\mathrm{B}}$, then the ratio ${\mathrm{T}}_{\mathrm{A}}/{\mathrm{T}}_{\mathrm{B}}$ is :-
