JEE Main & Advanced Physics Two Dimensional Motion Sample Paper Topic Test - Two Dimensional Motion

  • question_answer
    The range of a projectile for a given initial velocity is maximum when the angle of projection is \[{{45}^{o}}\]. The range will be minimum, if the angle of projection is

    A) \[{{90}^{o}}\]

    B) \[{{180}^{o}}\]

    C) \[{{60}^{o}}\]

    D) \[{{75}^{o}}\]

    Correct Answer: A

    Solution :

    [a] Range\[=\frac{{{u}^{2}}\sin 2\theta }{g}\]; when \[\theta =90{}^\circ \], \[R=0\] i.e. the body will fall at the point of projection after completing one dimensional motion under gravity.
