  • question_answer
    Rain water falls horizontally downwards with velocity v. When the velocity of air in horizontal direction is u, then water is store at the rate R m3/s. When the velocity of air becomes 2u, the rate of store of water will be

    A)  R                

    B)  R/2

    C)  2R             

    D)  R\[\frac{\sqrt{4{{u}^{2}}\,+\,{{v}^{2}}}}{\sqrt{{{u}^{2}}+{{v}^{2}}}}\]

    Correct Answer: A

    Solution :

     The rate of storage of rain water in any pot, depends upon vertical component of velocity. Therefore option [a] is correct.
