  • question_answer
    If the kinetic energy of a body increases by 0.1%, the percent increase of its momentum will be                [MP PMT 1994]

    A)                 0.05%   

    B)                 0.1%

    C)                 1.0%     

    D)                 10%

    Correct Answer: A

    Solution :

                        \[P=\sqrt{2\,mE}\]\\[P\propto \sqrt{E}\] Percentage increase in\[P=\frac{1}{2}\](percentage increase in E) = \[\frac{1}{2}(0.1%)=0.05%\]
