    A proton is about 1840 times heavier than an electron. When it is accelerated by a potential difference of 1 kV, its kinetic energy will be:

    A)  1840 keV            

    B)        1/1840 keV       

    C)  1 keV                   

    D)        920 keV

    Correct Answer: C

    Solution :

    When potential difference is V, energy is given by \[\beta \]          \[x\] The above equation shows that kinetic energy is independent of mass of charged particle. Hence, kinetic energy is 1 keV.
