    In an X-ray tube, electrons bombarded the target produce X-rays of minmum wavelength\[1\overset{0}{\mathop{A}}\,\]The energy of bombarding electron will be :

    A) 100 eV                 

    B) 14375 eV

    C) 12000 eV                             

    D) 12375 eV

    Correct Answer: D

    Solution :

                    Energy of bombarding electron is \[E=\frac{hc}{\lambda }=\frac{6.6\times {{10}^{-34}}\times 3\times {{10}^{8}}}{1\times {{10}^{-10}}}\] \[=19.8\times {{10}^{-16}}J\] \[E=\frac{19.8\times {{10}^{-16}}}{1.6\times {{10}^{-19}}}eV\] \[=12375eV\]
