A man running at a speed of \(5 \mathrm{~km} / \mathrm{h}\), find that the rain falls vertically. When he stops running, he finds that the rain is falling at an angle of \(60^{\circ}\) with the horizontal. The velocity of rain with respect to running man is
- A \(\frac{5}{\sqrt{3}} \mathrm{~km} / \mathrm{h}\)
- B \(\frac{5\sqrt{3}}{{2}} \mathrm{~km} / \mathrm{h}\)
- C \(\frac{4\sqrt{3}}{2} \mathrm{~km} / \mathrm{h}\)
