    An X-ray tube operates on 30 kV. The minimum wavelength emitted is,\[\frac{1}{200}s\],\[L=\frac{0.4}{\pi }\]\[R=30\Omega \] :

    A)  6.6 \[\Omega \]                                              

    B)  1.2\[\Omega \]

    C)  0.133 \[\Omega \]                         

    D)  0.4 \[\Omega \]

    Correct Answer: D

    Solution :

    Using relation \[{{\lambda }_{\min }}=\frac{hc}{eV}=\frac{12375\times {{10}^{-16}}}{3}=0.4\overset{\text{o}}{\mathop{\text{A}}}\,\]
