    The maximum range of a projectile is 100 m. The maximum height reached by it is

    A)  100 m                                  

    B)  25 m

    C)  200 m                                  

    D)  75 m

    Correct Answer: B

    Solution :

                     \[{{R}_{\max }}=\frac{{{u}^{2}}}{g}=100m\] The range of the projectile is maximum for the angle of projection\[\theta =45{}^\circ \]. When the range is maximum the height attained by a projectile is, \[H=\frac{{{u}^{2}}}{4g}=\frac{100}{4}=25\,m\]
