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

  • question_answer
    The greatest height to which a man can throw a stone is \[\sqrt{\frac{F}{m\,r}}\]. The greatest distance to which he can throw it, will be

    A) \[2\,\pi \,{{r}^{2}}/T\]

    B) \[\upsilon ,\,\upsilon \text{ and }\upsilon \]

    C) \[2h\]

    D) \[3h\]

    Correct Answer: C

    Solution :

    [c] For greatest height \[\theta =90{}^\circ \]       \[{{H}_{\max }}=\frac{{{u}^{2}}{{\sin }^{2}}(90{}^\circ )}{2g}=\frac{{{u}^{2}}}{2g}=h\] (given)                  \[{{R}_{\max }}=\frac{{{u}^{2}}{{\sin }^{2}}2(45{}^\circ )}{g}=\frac{{{u}^{2}}}{g}=2h\]
