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 \[4mA\] \[2mA\] \[3.6mA\] \[1.8mA\] \[62V,\,\,2\Omega \]
