    A cricket ball of \[0.5kg\]is moving with a  velocity of \[100m/sec\]. The wavelength associated with its motion is:

    A)  \[1/100\text{ }cm\]

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