  • question_answer
    The minimum wavelength of X-rays achive from the\[\alpha -\]ray tube is 0.1 A. The maximum voltage

    A)  \[1.25\times {{10}^{3}}V\]    

    B)  \[1.24\times {{10}^{4}}V\]

    C)  \[1.24\times {{10}^{5}}V\]      

    D)  \[1.24\times {{10}^{6}}V\]

    Correct Answer: C

    Solution :

     \[{{\lambda }_{\min }}=\frac{12375}{V}\overset{o}{\mathop{\text{A}}}\,\] \[V=\frac{12375}{\lambda }\]volt\[=\frac{12375}{0.1}\] \[V=1.24\times {{10}^{5}}volt\]
