A) \[1/\sqrt{2}\]
B) \[\sqrt{2}\]
C) \[2\sqrt{2}\]
D) \[1/2\sqrt{2}\]
Correct Answer: B
Solution :
Given, \[A={{60}^{o}}\]and \[{{\delta }_{m}}={{30}^{o}}\] As, \[\mu =\sin \frac{\left( \frac{A+{{\delta }_{m}}}{2} \right)}{\sin \left( \frac{A}{2} \right)}\] \[\Rightarrow \] \[\mu =\frac{\sin ({{45}^{o}})}{\sin ({{30}^{o}})}\] \[=\frac{1/\sqrt{2}}{1/2}=\sqrt{2}\]
