    The de-Broglie wavelenght of a particle with mass 1 kg and velocity 100 m/s is :

    A) \[6.6\times {{10}^{-33}}m\]                        

    B) \[6.6\times {{10}^{-36}}m\]

    C) \[3.3\times {{10}^{+33}}m\]                       

    D) \[3.3\times {{10}^{-36}}m\]

    Correct Answer: B

    Solution :

     \[\because \]                    \[\lambda =\frac{h}{mv}=\frac{6.6\times {{10}^{-34}}}{1\times 100}\]\[=6.6\times {{10}^{-36}}\,m\]
