    If for a given angle of projection, the horizontal range is doubled, the time of flight becomes:

    A)  \[\frac{1}{\sqrt{2}}\]times                         

    B)  \[\sqrt{2}\] times           

    C)         2 times               

    D)         4 times

    Correct Answer: B

    Solution :

    Since, time of flight\[T\propto \sqrt{R}\] (where R= horizontal range of flight) when R is doubled the time of flight will become \[\sqrt{2}\] times.
