Solution

Q.
A block of $\sqrt{3}$ kg is attached to a string whose other end is attached to the wall. An unknown force F is applied so that the string makes an angle of 30° with the wall. The tension T is (Given g = 10 ${ms}^{- 2}$ ) [2023]

1 20 N

2 25 N

3 10 N

4 15 N

Ans.
(1)

$\cos θ = \frac{\sqrt{3} g}{T}$

$\Rightarrow \frac{\sqrt{3}}{2} = \frac{\sqrt{3} g}{T}$

$\Rightarrow T = 20 N$
