    The order of the size of nucleus and Bohr radius of an atom respectively are       [MP PET 2001; MP PMT 2001]

    A)            \[{{10}^{-14}}m,\ {{10}^{-10}}m\]                                   

    B)            \[{{10}^{-10}}\,m,\,{{10}^{-8}}\,m\]

    C)            \[{{10}^{-20}}m,\ {{10}^{-16}}m\]                                   

    D)            \[{{10}^{-8}}\,m,\,{{10}^{-6}}\,m\]

    Correct Answer: A

    Solution :

               Diameter of nucleus is of the order of 10?14m and radius of first Bohr orbit of hydrogen atom \[r=0.53\times {{10}^{-10}}m.\]
