    An X-ray photon has a wavelength 0.01\[\overset{0}{\mathop{A}}\,\]. Its momentum \[(in\text{ }kg\text{ }m{{s}^{-1}})\] is :

    A) \[6.66\times {{10}^{-22}}\]                         

    B) \[3.3\times {{10}^{-32}}\]

    C) \[6.6\times {{10}^{-22}}\]                            

    D)  0

    Correct Answer: C

    Solution :

                    From the relation of momentum and wave length \[p=\frac{h}{\lambda }\] (Here:  \[\lambda =0.01\overset{\text{o}}{\mathop{\text{A}}}\,,\,h=6.6\times {{10}^{-34}}Js\]) \[p=\frac{6.6\times {{10}^{-34}}}{0.01\times {{10}^{-10}}}=6.6\times {{10}^{-22}}kgm/s\]
