A man walking along a straight line with a velocity \(6 \mathrm{~km} / \mathrm{h}\) encounters rain falling vertically down with a velocity \(6 \sqrt{3} \mathrm{~km} / \mathrm{h}\). At what angle the man should hold his umbrella so that he can protect himself from rain
- A \(30^{\circ}\) with respect to ground
- B \(30^{\circ}\) with respect to vertical
- C \(45^{\circ}\) with respect to ground
- D \(60^{\circ}\) with respect to vertical
Answer & Solution
Correct Answer
(B) \(30^{\circ}\) with respect to vertical
Step-by-step Solution
Detailed explanation
\[ \mathrm{v}_{\mathrm{V}}=6 \sqrt{3} \mathrm{~km} / \mathrm{h} \] \[ \begin{aligned} & \tan \alpha=\frac{6}{6 \sqrt{3}}=\frac{1}{\sqrt{3}} \\ & \tan \alpha=\tan 30^{\circ} \end{aligned} \] \(\alpha=30^{\circ}\) with respect to vertical
