    A body of mass m is projected horizontally with a velocity v from the top of a tower of height h and it reaches the ground at a distance x from the foot of the tower. If a second body of mass 2m is projected horizontally from the top of a tower of height 2h, it reaches the ground at a distance 2x from the foot of the tower. The horizontal velocity of the second body is

    A) \[~v\]               

    B)        \[2v\]

    C) \[\sqrt{2v}\]                  

    D)        \[v/2\]

    Correct Answer: C

    Solution :

    [c] \[x=v\sqrt{\frac{2h}{g}},\text{ }2x=v'\sqrt{\frac{2\left( 2h \right)}{g}}=\sqrt{2}v\]
