An object A of mass ' $m$ ' is located at a point ' $\mathrm{P}$ ' at distances ' $\mathrm{r}$ ' and ' $2 \mathrm{r}$ ' from two planets $B$ and $C$ of masses ' $M$ ' and ' $6 M$ ' respectively as shown in the figure. If the escape speed of the object A from point ' $\mathrm{P}$ ' due to the gravitational influence of only planet B is $5 \mathrm{kms}^{-1}$, then the escape speed of the object A from point ' $\mathrm{P}$ ' due to the gravitational influence of both the planets is ____ $\mathrm{kms}^{-1}$.
