Physics - Gravitation Question with Solution | TestHub

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