A spaceship is sent to investigate a planet of mass M and radius R. While hanging motionless in space at a distance 5R from the centre of the planet the spaceship fires an instrument package of mass m which is much smaller than the mass of the spaceship. The angle θ for which the package just grazes the surface of the planet is
