A) \[\frac{\pi }{4}\]
B) \[\frac{\pi }{6}\]
C) \[\frac{\pi }{3}\]
D) \[0{}^\circ \]
Correct Answer: C
Solution :
[c] \[{{r}_{1}}=0\] \[{{r}_{2}}=\sqrt{3\hat{i}}+3\hat{j}\] Slope = tan \[\theta =\frac{{{r}_{y}}}{{{r}_{x}}}=\frac{3}{\sqrt{3}}\] \[tan\theta =\sqrt{3}\] \[\theta =60{}^\circ \,\,or\frac{\pi }{3}\]You need to login to perform this action.
