JEE MainPhysicsGravitationMCQ+4 / −1
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)
