Physics - Gravitation Question with Solution | TestHub

Two planets $A$ and $B$ having masses $m_1$ and $m_2$ move around the sun in circular orbits of $r_1$ and $r_2$ radii respectively. If angular momentum of $A$ is $L$ and that of $B$ is $3\mathrm{L}$, the ratio of time period $\left(\frac{T_A}{T_B}\right)$ is:
