Two planets A and B having masses $\displaystyle \mathrm{m}_1$ and $\displaystyle \mathrm{m}_2$ move around the sun in circular orbits of $\displaystyle \mathrm{r}_1$ and $\displaystyle \mathrm{r}_2$ radii respectively. If angular momentum of A is L and that of B is $\displaystyle 3$ L , the ratio of time period $\displaystyle \left(\frac{T_A}{T_B}\right)$ is:
