JEE Main 2019 — Gravitation Question with Solution

Two stars of masses 3 $$\times$$ 10³¹ kg each, and at distance 2 $$\times$$ 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 $$\times$$ 10^–11 Nm² kg^–2)
