The graph shows how the extension of a spring changes with the masses suspended from it when the spring is on planet X and when the spring is on planet Y. Which conclusion can be drawn from these graphs?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
AIt is not possible to compare the gravitational field strengths on planets X and Y.
BThe gravitational field strength on planet X is equal to the gravitational field strength on planet Y.
CThe gravitational field strength on planet X is one third of the gravitational field strength on planet Y.
DThe gravitational field strength on planet X is three times the gravitational field strength on planet Y.
✓ Correct answer
D: The gravitational field strength on planet X is three times the gravitational field strength on planet Y.
