A particle is projected from a point A which is at a distance 8R from the centre of the earth and with speed V in a direction making 30 with the line joining the centre of the earth and point A as shown Find the speed V if the particle passes grazing the surface of the earth Consider gravitational interaction only between these two use GM 6 4 x 107 m s R 8R Fot 30 R 1000 112 m s 15 m s 8000 2 8000 2 m s None of these
