A) \[{{Y}_{B}}=2{{Y}_{A}}\]
B) \[{{Y}_{A}}={{Y}_{B}}\]
C) \[{{Y}_{B}}=3{{Y}_{A}}\]
D) \[{{Y}_{A}}=3{{Y}_{B}}\]
Correct Answer: D
Solution :
\[\frac{{{Y}_{A}}}{{{Y}_{B}}}=\frac{\tan {{\theta }_{A}}}{\tan {{\theta }_{B}}}=\frac{\tan 60}{\tan 30}=\frac{\sqrt{3}}{1/\sqrt{3}}=3\Rightarrow {{Y}_{A}}=3{{Y}_{B}}\]You need to login to perform this action.
