A) \[{{90}^{o}}\]
B) \[{{30}^{o}}\]
C) \[{{60}^{o}}C\]
D) data is incomplete
Correct Answer: C
Solution :
From the figure, we have \[\Rightarrow \] \[\tan \theta =\frac{{{X}_{L}}-{{X}_{C}}}{R}\] Taking \[{{X}_{C}}=0\] and here \[{{X}_{L}}=3R\] \[\Rightarrow \] \[\theta ={{\tan }^{-1}}\sqrt{\frac{3R}{R}}\] \[\Rightarrow \] \[\theta ={{\tan }^{-1}}\sqrt{3}\,=\,{{60}^{o}}\] \[(\because \,\,\tan {{60}^{o}}=\sqrt{3})\]You need to login to perform this action.
