    The energy of a hydrogen atom in its ground state is -13.6eV. The energy of the level corresponding to the quantum number n = 5 is

    A) -5.40eV                               

    B)  -0.54eV

    C)  -8.5eV                                 

    D) -2.72eV

    Correct Answer: B

    Solution :

    The energy of the hydrogen atom in nth state is given by\[-\frac{1}{48}\] Here,        n = 5 \[f(x)=[x]+\left[ x+\frac{1}{2} \right]\]\[x=\frac{1}{2}\]
