An object is in a uniform gravitational field. The graph shows how the change in gravitational potential energy ΔE_P of the object varies with the vertical distance x moved by the object from a fixed point. Which graph shows how the gravitational force F acting on the object varies with distance x?

1. AGraph A: F against x, straight line through origin with positive gradient
2. BGraph B: F against x, straight line with positive gradient starting from positive F at x = 0
3. CGraph C: F against x, horizontal line at constant positive F
4. DGraph D: F against x, straight line with negative gradient starting from positive F at x = 0
