    Forces exerted by a uniform electric field on an electron having mass me and proton of mass mp are represented as Fe and Fp respectively are related as:

    A) \[{{F}_{p}}={{F}_{e}}\]                                  

    B) \[\frac{{{F}_{e}}}{{{F}_{p}}}=\frac{{{m}_{e}}}{{{m}_{p}}}\]

    C) \[\frac{{{F}_{e}}}{{{F}_{p}}}=\frac{{{m}_{e}}}{{{m}_{p}}}\]                          

    D) \[\frac{{{F}_{e}}}{{{F}_{p}}}=\frac{m_{e}^{2}}{m_{p}^{2}}\]

    Correct Answer: A

    Solution :

                     The force (F) on charge q due to electric field strength E is \[F=qE\] Given, E is uniform, hence \[{{F}_{p}}={{F}_{e}}\]
