A \( 1 \mathrm{~N} \) pendulum bob is held at an angle \( \theta \) from the vertical by a \( 2 \mathrm{~N} \) horizontal force \( \mathrm{F} \) as shown in the
P figure. The tension in the string supporting the

W pendulum bob (in newton) is
(1) \( \cos \theta \)
(2) \( \frac{2}{\cos \theta} \)
(3) \( \sqrt{5} \)
(4) 1
