    When a projectile is fired with initial velocity u at an angle of projection 6, then its range is R. If the initial velocity is doubled at same angle of projection, then the new range will be

    A)  \[R\]                                    

    B)  \[\frac{R}{2}\]

    C)  \[2R\]                                  

    D)  \[4R\]

    Correct Answer: D

    Solution :

                    The range of a projectile, \[R=\frac{{{u}^{2}}\sin 2\theta }{g}\]\[\Rightarrow \]\[R\propto {{u}^{2}}\] So, if the velocity is doubled then range will becomes 4 times.
