    The total energy of the electron in the hydrogen atom in the ground state is -13.6 eV. The KE of this electron is

    A)  13.6 eV  

    B)  zero

    C)  -13.6 eV    

    D)  6.8 eV

    Correct Answer: A

    Solution :

    \[\because \]\[KE=\frac{1}{2}m{{v}^{2}}=\frac{Z{{e}^{2}}}{2r};TE=-\frac{Z{{e}^{2}}}{2r}\]
