    A projectile fired with initial velocity u at some jl angle \[\theta \] has a range R. If the initial velocity be j doubled at the same angle of projection, then the range will be

    A) 2R                               

    B) R/2

    C) R                                 

    D) 4R

    Correct Answer: D

    Solution :

    \[R=\frac{{{u}^{2}}\sin \,\,2\theta }{g}\,\,\,\,\therefore \,\,\,R\propto {{u}^{2}}\]. If initial velocity be doubled, then the range will become four times.
