    The kinetic energy of an electron, which isaccelerated in the potential difference of 100V, is:

    A)  \[1.6\times {{10}^{-17}}J\]                         

    B)  \[1.6\times {{10}^{-14}}J\]

    C)  \[1.6\times {{10}^{-10}}J\]                         

    D) \[1.6\times {{10}^{-8}}J\]

    Correct Answer: A

    Solution :

                     \[KE=eV\] \[=1.6\times {{10}^{-19}}\times 100\]                 \[=1.6\times {{10}^{-17}}\,J\]
