A) \[\sqrt{\frac{5}{3}}\]
B) \[\frac{4}{3}\]
C) \[\frac{5}{\sqrt{3}}\]
D) \[\frac{3}{\sqrt{5}}\]
Correct Answer: D
Solution :
\[\tan \,\theta \,\,\,=\,\,\frac{1.5}{\mu }\,;\,\,\,Sin\,\theta \,\,=\,\,\frac{1}{\mu }\] \[\frac{1}{\sqrt{{{\mu }^{2}}-1}}\,\,=\,\,\,\frac{3}{2\mu }\] \[4{{\mu }^{2}}\,\,=\,\,\,9({{\mu }^{2}}-1)\] \[5{{\mu }^{2}}\,=\,\,9\] \[\mu \,\,=\,\,\frac{3}{\sqrt{5}}\]You need to login to perform this action.
