Q.
A body of weight 2 kg is suspended as shown in figure. The tension $T_{1}$ in the horizontal string (in kg-wt) is
A) $2/\sqrt{3}$
B) $\sqrt{3}/2$
C) $2\sqrt{3}$
D) 2
Explanation
(c) $T\sin{30{^\circ} = 2\ kg}$-wt
[image:5_image257.jpeg]
$\Longrightarrow \ \ T = 4$ kg-wt
$T_{1} = T\cos{30{^\circ} = 4\cos{30{^\circ} = 2\sqrt{3}}}$
