    In terms of Bohr radius \[{{a}_{0}}\] the radius of second Bohr orbit of hydrogen atom is given by

    A)  \[4\,{{a}_{0}}\]                                

    B)  \[8\,{{a}_{0}}\]

    C)  \[\sqrt{2}\,{{a}_{0}}\]                  

    D)  \[2\,{{a}_{0}}\]

    E)                  \[\sqrt{4}\,{{a}_{0}}\]

    Correct Answer: A

    Solution :

                    Since, \[r\propto {{\pi }^{2}},\] therefore radius of second Bohrs orbit is\[4{{a}_{0}}\].
