10 kg wt is suspended as shown below then Tension ${\text{T}}_{\text{1}}\&{\text{T}}_{\text{2}}$ are

 

${\text{T}}_{\text{3}}=100\text{N}$

$\frac{{\text{T}}_{\text{1}}}{\text{1}}=\frac{{\text{T}}_{\text{2}}}{\cos 30°}=\frac{100}{\cos 60°}$

${\text{T}}_1=\frac{100}{\frac{\sqrt{3}}{2}}$

$=\frac{200}{\sqrt{3}}\text{N}=\frac{20}{\sqrt{3}}\text{kgwt}$

$\frac{{\text{T}}_{\text{2}}}{\frac{1}{2}}=\frac{100}{\frac{\sqrt{3}}{2}}$

${\text{T}}_{\text{2}}=\frac{100}{\sqrt{3}}$

${\text{T}}_{\text{2}}=\frac{10}{\sqrt{3}}\text{kg}\text{.wt}$
