    The range of a projectile is R when the angle of projection is \[40{}^\circ \]. For the same velocity of projection and range, the other possible angle of projection is

    A) \[45{}^\circ \]              

    B)        \[50{}^\circ \]  

    C) \[60{}^\circ \]              

    D)        \[40{}^\circ \]

    Correct Answer: B

    Solution :

    [b] Horizontal range R =\[\frac{{{\text{u}}^{2}}\sin 2\theta }{\text{g}}\]. Range is same for angle of projection \[\theta \] and \[(90{}^\circ -\theta ).\]
