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 figure. The tension in the string supporting the pendulum bob (in newton) is
- A \(\cos \theta\)
- B \(\frac{2}{\cos \theta}\)
- C \(\sqrt{5}\)
- D 1
Answer & Solution
Correct Answer
(C) \(\sqrt{5}\)
Step-by-step Solution
Detailed explanation
As the bob is in equilibrium under the effect of three forces \(-T, F\) and \(W\) \(\therefore \quad \mathbf{T}+\mathbf{P}+\mathbf{W}=0\) From Eqs. (i) and (ii) \(T^2=W^2+F^2\)…
