Question

A body of weight 2 kg is suspended as shown in the figure. The tension $\mathrm{T}_{1}$ in the horizontal string (in kgwt) is\

Professor PC Thomas Classes · Answer

(C)\  As the body is in equilibrium vertical forces balance each other. Now $\operatorname{Tsin} 30^{\circ}=2 \mathrm{~g}$\ $\mathrm{T}=4 \mathrm{~g}$.Horizontal forces balance each other $	herefore \mathrm{T} \cos 30^{\circ}=\mathrm{T}_{1}$;\ $\mathrm{T}_{1}=4 \mathrm{~g} 	imes \frac{\sqrt{3}}{2}=2 \sqrt{3} \mathrm{~g}=2 \sqrt{3}$ in kg wt.
