CAPE Physics Unit 1 · 2011 · Paper 1 · Question Q1
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?
- (A)
T = W - (B)
T = H - (C)
T = W / \cos\theta - (D)
T = H / \cos\theta
