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

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