A metal sphere is hung by a string fixed to a wall. The sphere is pushed away from the wall by a stick. The forces acting on the sphere are shown in the second diagram. Which of the following statements is wrong
(a) \( P=W \tan \theta \)
(b) \( \vec{T}+\vec{P}+\vec{W}=0 \)
(c) \( T^{2}=P^{2}+W^{2} \)
(d) \( T=P+W \)
