    The kinetic and potential energy (in eV) of an electron present in third Bohr's orbit of hydrogen atom are respectively:

    A) \[-1.51.-3.02\]                

    B) \[1.51,-3.02\]

    C) \[-3.02,1.51\]     

    D) \[1.51,-1.51\]

    Correct Answer: B

    Solution :

    [b] Total energy of third shell \[=\frac{-13.6}{{{3}^{2}}}\] \[=-1.51\text{ }eV\] K.E. = - Total energy \[\Rightarrow 1.51\text{ }eV\] \[P.E.=2\times T.E.=-3.02eV\]
