A) \[10\text{ }m\]
B) \[~20\text{ }m\]
C) \[\left( \text{20/}\sqrt{3} \right)\text{ m }\!\!~\!\!\text{ }\]
D) \[\left( 10/\sqrt{3} \right)\text{ m}\]
Correct Answer: D
Solution :
[d] \[\tan \theta =\frac{{{\text{u}}^{2}}}{\text{Rg}}\] \[\Rightarrow \text{R}\,\,\text{=}\frac{{{\text{u}}^{2}}}{g\tan \theta }=\frac{100}{10\times \sqrt{3}}=\frac{10}{\sqrt{3}}\text{ m}\]
