The diagram depicts a ball of weight $W$ suspended in equilibrium by a string. The string makes an angle $\theta$ with the vertical. The tension in the string is $T$. A horizontal force $P$ from a metal rod keeps the ball away from the wall. What is the relationship between the magnitudes of $T$, $P$ and $W$?
- A$P = T \cos \theta$ and $W = T \sin \theta$
- B$T = P + W$
- C$T^2 = P^2 + W^2$
- D$W = P \tan \theta$ and $W = T \cos \theta$
