Rain water is falling vertically downward with velocity ` v`, When velocity of wind is `u` in horizontal direction, water is collected at the rate of `R m^3`/s when velocity of wind becomes `2u` in horizontal direction . The rate of collection of water in vessel is
The rate of storing water in vessel depends upon vertical component of velocity . In this problem , vertical component of velocity in both cases are same .
Hence , (A ) is correct.
