Two axial members, namely $\text{OP}$ and $\text{OQ}$, are pin joined at $\text{O}$ as shown in the figure. A force $F$ acts at point $\text{P}$ along the positive $x$ direction and a force $\sqrt{3} F$ acts at point $\text{Q}$ along the positive $y$ direction.
The resultant of the applied forces makes an angle $\theta$ (anticlockwise from the positive $x$ -axis).
The value of $\theta$ is $\_\_\_\_$.
