    The minimum wavelength of X-ray emitted by X-ray tube is \[0.4125\,\overset{\text{o}}{\mathop{\text{A}}}\,\]. The accelerating voltage is:

    A)  30 kV       

    B)                        50 kV                   

    C)  80 kV                   

    D)         60 kV

    Correct Answer: A

    Solution :

    From the formula \[eV=h\frac{c}{\lambda }\] \[V=\frac{hc}{e\lambda }=\frac{6.6\times {{10}^{-34}}\times 3\times {{10}^{8}}}{1.6\times {{10}^{-19}}\times 0.4125\times {{10}^{-10}}}\]                    \[=30\times {{10}^{3}}volt=30\,kvolt\]
