    A 0.66 kg ball is moving with a speed of 100 m/s. The associated wavelength will be\[(h=6.6\times {{10}^{-34}}Js)\]     [AIPMT (M) 2010]

    A)  \[6.6\times {{10}^{-32}}m\]    

    B)  \[6.6\times {{10}^{-34}}m\]    

    C)  \[1.0\times {{10}^{-35}}m\]    

    D)       \[1.0\times {{10}^{-32}}m\]

    Correct Answer: C

    Solution :

    From de-Broglie equation,
    \[\lambda =\frac{h}{mv}=\frac{6.6\times {{10}^{-34}}}{0.66\times 100}={{10}^{-35}}m\]
