A rubber ball of weight, W, is suspended from a support and is being displaced laterally at an angle, \theta^\circ, from the vertical by a wind of constant force (H). The ball is in equilibrium and the tension in the string is T. Which of the following equations is correct?

1. (A)T = W
2. (B)T = H
3. (C)T = W / \cos\theta
4. (D)T = H / \cos\theta

This question uses a figure or table from the paper — you'll see it when you practise.
