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

  • question_answer
    A projectile fired with initial velocity \[u\] at some angle \[\theta \] has a range \[R\]. If the initial velocity be 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 :

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