  • question_answer
    Two bodies with kinetic energies in the ratio of 4 : 1 are moving with equal linear momentum. The ratio of their masses is                                             [CBSE PMT 1999]

    A)                 1 : 2       

    B)                 1 : 1

    C)                 4 : 1       

    D)                 1 : 4

    Correct Answer: D

    Solution :

                        \[E=\frac{{{p}^{2}}}{2m}\] \ \[m\propto \frac{1}{E}\] (If momentum are constant)                 \[\frac{{{m}_{1}}}{{{m}_{2}}}=\frac{{{E}_{2}}}{{{E}_{1}}}=\frac{1}{4}\]
