A person walks at the rate of \[3\,km/hr\]. Rain appears to him in vertical direction at the rate of \[3\sqrt{3}km/hr\]. Find the magnitude and direction of true velocity of rain.

\[6\,km/hr\], inclined at an angle of \[60{}^\circ \] to the vertical towards the person's motion.

\[6\,km/hr\], inclined at an angle of \[45{}^\circ \] to the vertical towards the person's motion.

\[3\,km/hr\], inclined at an angle of \[30{}^\circ \] to the vertical towards the person's motion.

\[6\,km/hr\], inclined at an angle of \[30{}^\circ \] to the vertical towards the person's motion.
