A kite is in equilibrium at the end of a string, as shown. [Figure 13.1] The kite has three forces acting on it: the weight W, the tension T in the string, and the force F from the wind. Which vector diagram represents the forces acting on the kite?
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.
Adiagram showing the three force vectors (W, T, F) arranged tail-to-head, forming a closed triangle.
Bdiagram showing the three force vectors (W, T, F) arranged tail-to-head, forming an open path (not in equilibrium), where W points downwards, T points up-left, F points down-left.
Cdiagram showing the three force vectors (W, T, F) arranged tail-to-head, forming an open path (not in equilibrium), where W points downwards, T points up-left, F points up-left.
Ddiagram showing the three force vectors (W, T, F) arranged tail-to-head, forming an open path (not in equilibrium), where W points downwards, T points up-right, F points right.
✓ Correct answer
A: diagram showing the three force vectors (W, T, F) arranged tail-to-head, forming a closed triangle.
