    In the Bohr Model of hydrogen atom, the electron circulates around the nucleus in a path of radius \[5.1\times {{10}^{-11}}\] m at a frequency of \[6.8\times {{10}^{15}}\] revolutions per second. What will be the equivalent current?

    A)  2.544 mA           

    B)  2.176 mA

    C)  1.880 mA           

    D)  1.088 mA

    Correct Answer: D

    Solution :

                     In the Bohr model of hydrogen atom,                 \[I=\frac{q}{t}=q\times V\]                 \[=(1.6\times {{10}^{-19}})\times (6.8\times {{10}^{15}})\]                 = 1.088 mA
