    In a hydrogen atom, the electron in a given orbit has total energy\[-1.5\text{ }eV\]. The potential energy is

    A)  1.5 eV                 

    B) \[-1.5\text{ }eV\]

    C)  3.0 eV                                 

    D) \[-3.0\text{ }eV\]

    Correct Answer: D

    Solution :

                     Potential energy\[=2\times Total\text{ }energy\] \[=2\times (-1.5)\] \[=-3.0eV\]
