A particle is projected from point A, that is at a distance 4R from the centre of the Earth, with speed v1 in a direction making 30 with the line joining the centre of the Earth and point A, as shown. Find the speed v1 of particle (in m/s) if particle passes grazing the surface of the earth. Consider gravitational interaction only between these two.
