  • question_answer
    The angle of projection at which the horizontal range and maximum height of projectile are equal is

    A) \[{{45}^{o}}\]

    B) \[\theta ={{\tan }^{-1}}(0.25)\]

    C) \[\theta ={{\tan }^{-1}}4\]or \[(\theta =76{}^\circ )\]

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

    Correct Answer: C

    Solution :

    [c] \[R=4H\cot \theta .\] When \[R=H\] then \[\cot \theta =1/4\]\[\Rightarrow \theta ={{\tan }^{-1}}(4)\]
