Two parallel forces, each of magnitude F, act on a rod of length 5d. Which diagram shows the positions of the two forces that will produce the largest torque on the rod?
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.
Arod with forces F acting inwards at each end.
Brod with forces F acting downwards at each end.
Crod with two opposite forces F acting 2d apart, offset from the center.
Drod with two opposite forces F acting 2d apart, centered on the rod.
✓ Correct answer
D: rod with two opposite forces F acting 2d apart, centered on the rod.
