Rain water is falling vertically downwards with velocity v, when the velocity of wind is zero,
water is collected at a rate R. When the wind starts blowing horizontally at a speed u, the rate of collection of water in the same vessel is:
A
B
C
D
R
Text Solution
Verified by ExpertsThe correct answer is:
D
Rate of collection (R) 
is the angle between the velocity of the rain and area of
vessel)
When the wind blows 
, ( 
is the new velocity of rain)
