    The ground state energy of hydrogen atom is ? 13.6 eV. What is the potential energy of the electron in this state                                                                                              [AIIMS 2005]

    A)            0 eV                                         

    B)            ? 27.2 eV

    C)            1 eV                                         

    D)            2 eV

    Correct Answer: B

    Solution :

               P.E.\[=2\times \text{Total energy}=\text{2}\times (-13.6)=-\text{27}\text{.2}\,\text{eV}\]
