    The electric potential at the surface of anatomic nucleus (Z = 50) of radius\[9.0\times {{10}^{-13}}cm\] is :

    A)  \[9\times {{10}^{5}}volt\]                           

    B)  \[8\times 106\,volt\]

    C)  80 volt                                 

    D)  9 volt

    Correct Answer: B

    Solution :

                    Electric potential at the surface of an atomic nucleus is \[V=\frac{1}{4\pi {{\varepsilon }_{0}}}.\frac{Ze}{r}\] \[=\frac{9\times {{10}^{9}}\times 50\times 1.6\times {{10}^{-19}}}{9\times {{10}^{-15}}}\] \[=8\times {{10}^{6}}volt\]
