A) \[30{}^\circ \]
B) \[45{}^\circ \]
C) \[60{}^\circ \]
D) \[0{}^\circ \]
Correct Answer: C
Solution :
Draw the situation as shown. OA represents the path of the particle starting from origin O (0, 0). Draw a perpendicular from point A to x-axis. Let path of the particle makes an angle \[\theta \] with the x-axis, then \[\tan \theta =\] slope of line OA \[=\frac{AB}{OB}=\frac{3}{\sqrt{3}}=\sqrt{3}\] or \[\theta =60{}^\circ \]You need to login to perform this action.
