Rain is falling vertically downwards with a velocity of 4 km/h. A man walks in the rain with a velocity of 3 km/h. The raindrops will falls on the man with a velocity of

A)  \[1.25\times {{10}^{3}}m/s\]                    

B)  \[\frac{hv}{4}\]

C)  \[\frac{hv}{3}\]               

D)  \[\frac{hv}{2}\]

Correct Answer: D

Solution :

                                Relative velocity of man w.r.t. rain \[4mA\] \[2mA\] \[3.6mA\] \[1.8mA\] \[62V,\,\,2\Omega \]
