Q. A small sphere is hung by a string fixed to a wall. The sphere is pushed away from the wall by a stick. The force acting on the sphere are shown in figure. Which of the following statements is wrong?

A) $P = Wtan\theta$
B) $\overrightarrow{T} + \overrightarrow{P} + \overrightarrow{W} = 0$
C) $T^{2} = P^{2} + W^{2}$
D) $T = P + W$
Explanation

(d) Here $W = T$($cos\theta + sin\theta$)$< T$
so $P + Q = T$($cos\theta + sin\theta$)$< T$
Where as (a), (b) and (c) are correct and (d) is wrong.
