    A stone is thrown with a velocity u making an angle \[\theta \] with the horizontal. The horizontal distance covered by its fall to ground is maximum when the angle \[\theta \] is equal to

    A) \[0{}^\circ \]                

    B)        \[30{}^\circ \]

    C) \[45{}^\circ \]

    D)        \[90{}^\circ \]

    Correct Answer: C

    Solution :

    [c] Since Range on horizontal plane is      \[R=\frac{{{u}_{2}}\sin 2\theta }{g}\] so it is max when sin\[2\theta =1\]\[\Rightarrow \]\[\theta =\frac{\pi }{4}\]
