A) \[\sqrt{3}:1\]
B) \[1:\sqrt{3}\]
C) \[2:\sqrt{3}\]
D) \[\sqrt{3}:2\]
Correct Answer: A
Solution :
For the equilibrium of the point O, the horizontal components of the tensions must be equal. \[{{T}_{1}}\sin {{30}^{o}}={{T}_{2}}\sin {{60}^{o}}\] or, \[{{T}_{1}}\times \frac{1}{2}={{T}_{2}}\frac{\sqrt{3}}{2}\] or, \[\frac{{{T}_{1}}}{{{T}_{2}}}=\sqrt{3}\] Hence, the correction option is (a).You need to login to perform this action.
