Two stars of masses $\displaystyle 3 \times 10^{31} \mathrm{~kg}$ each, and at distance $\displaystyle 2 \times 10^{11} \mathrm{~m}$ rotate in a plane about their common centre of mass O. A meteorite passes through O moving perpendicular to the star's rotation plane. In order to escape from the gravitational field of this double star, the minimum speed that meteorite should have at O is : (Take Gravitational constant $$\left.\mathrm{G}=6.67 \times 10^{-11} \mathrm{Nm}^2 \mathrm{~kg}^{-2}\right) $$
