← A small heavy ball is fixed to one end of a light rigid rod of length l. The other end of the rod is pivoted so that the ball can turn in a vertical circle. In a second set-up, the same ball hangs from a light string of the same length. In each case the ball is given a horizontal push at the lowest point. The least speeds at the lowest point that let the ball go round the full circle areTreat the Earth as a uniform solid sphere of radius R. Which graph shows how the acceleration due to gravity, g, changes with the distance r from the centre of the Earth, from the centre to well outside the surface? →
