A) \[\frac{3}{7}\]
B) \[\frac{3}{4}\]
C) \[{{\tan }^{-1}}\,(\sin \,i)\]
D) \[\frac{4}{5}\]
Correct Answer: B
Solution :
We know that, \[{{C}_{2}}\] But \[{{C}_{4}}\] or \[\frac{22}{3}\] \[\frac{3}{22}\] \[\frac{7}{4}\] or \[\frac{4}{7}\] \[\overset{0}{\mathop{A}}\,\] \[2\mathbf{\hat{i}}+3\mathbf{\hat{j}}+8\mathbf{\hat{k}}\] or \[4\mathbf{\hat{j}}-4\mathbf{\hat{i}}+\alpha \mathbf{\hat{k}}\] or \[-1\] The critical angle for pair of media or \[\frac{1}{2}\]You need to login to perform this action.
