  • question_answer
    Four particles given, have same momentum. Which has maximum kinetic energy

    A) Proton

    B) Electron

    C) Deutron

    D) a-particles

    Correct Answer: B

    Solution :

    [b]   \[\operatorname{E}=\frac{{{P}^{2}}}{2m}\therefore E\propto \frac{1}{m}\]     [If P= constant] i.e. the lightest particle will possess maximum kinetic energy and in the given
