How are forces able to act at a distance
WebAt a distance 2R from the centre of the Earth gravitational field strength is 2.5 newton kilogram-1. At a distance 3R from the centre of the Earth gravitational field strength is 1.1 newton kilogram-1. The rule is that if you: Double the distance from the centre of the Earth, the force will be four times weaker.
