(a) (i) Define gravitational field strength and state whether it is a scalar or vector quantity. A mass m is at a height h above the surface of a planet (ii) of mass M and radius R. The gravitational field strength at height h is g. By considering the gravitational force acting on massm, derive an equation from Newton's law of gravitation to express g in terms of M, R, h and the gravitational conșțant G.
