A) \[1\,\,:\,\,3\]
B) \[1\,\,:\,\,2\]
C) \[1\,\,:\,\,\sqrt{3}\]
D) \[\sqrt{3}\,\,:\,\,1\]
Correct Answer: A
Solution :
The line having greater slope has greater velocity. \[\therefore \] line making angle \[60{}^\circ \] with time axis has greater velocity. \[\frac{{{v}_{m}}}{{{v}_{n}}}=\frac{\tan \,30{}^\circ }{\tan \,60{}^\circ }\] \[=\,\,\frac{1/\sqrt{3}}{\sqrt{3}}=\frac{1}{3}\]You need to login to perform this action.
