    The de-Broglie wavelength of 1 kg mass moving with a velocity of 10 m/s, will be :

    A)  \[6.626\times {{10}^{-35}}m\]                  

    B)  \[6.626\times {{10}^{-34}}m\]

    C)  \[6.626\times {{10}^{-33}}m\]                  

    D)  none of these

    Correct Answer: A

    Solution :

                    Using the relation \[\lambda =\frac{h}{m\upsilon }=\frac{6.626\times {{10}^{-34}}}{1\times 10}\] \[=6.626\times {{10}^{-35}}m\]
