    A cricket ball of 0.5 kg is moving with a velocity of 100 m/s. The wavelength associated with its motion is

    A)  \[1\text{/}100\,cm\]                    

    B)  \[6.6\times {{10}^{-34}}m\]

    C)  \[1.32\times {{10}^{-35}}m\]    

    D)  \[6.6\times {{10}^{-28}}m\]

    Correct Answer: C

    Solution :

                    From de-Broglie equation \[\lambda =\frac{h}{mv}\] \[=\frac{6.62\times {{10}^{-34}}}{0.5\times 100}=1.32\times {{10}^{-35}}m\]
