    Two protons A and B are placed in space between plates of a parallel plate capacitor charged upto V volts (See fig.) Forces on protons are \[{{F}_{A}}\] and \[{{F}_{B}}\], then           [RPET 1999]

    A)            \[{{F}_{A}}>{{F}_{B}}\]

    B)            \[{{F}_{A}}<{{F}_{B}}\]

    C)            \[{{F}_{A}}={{F}_{B}}\]

    D)            Nothing can be said

    Correct Answer: C

    Solution :

               \[{{F}_{A}}={{F}_{B}}\]; because an uniform electric field produced between the plates.
