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?
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.
