Two stars of masses 3×10³¹ kg each, and at distance 2×10¹¹ 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 G=6.67×10⁻¹¹ Nm²/kg²)<p></p>
