The following force-extension graphs are drawn to the same scale. Which graph represents the deformed object with the greatest amount of elastic potential energy? [Figure 23.1]
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.
Aforce-extension graph showing a shallow, straight line
Bforce-extension graph showing a steep, straight line
Cforce-extension graph showing a steep curve bending towards the force axis
Dforce-extension graph showing a curve bending towards the extension axis
✓ Correct answer
B: force-extension graph showing a steep, straight line
