JEE Main & Advanced Physics Photo Electric Effect, X- Rays & Matter Waves Question Bank Self Evaluation Test - Dual Nature of Radiation and Matter

  • question_answer
    A homogeneous ball (mass = m) of ideal black material at rest is illuminated with a radiation having a set of photons (wavelength = X), each with the same momentum and the same energy. The rate at which photons fall on the ball is n. The linear acceleration of the ball is

    A) \[m\lambda /nh\]

    B) \[nh/m\lambda \]

    C) \[nh/m\lambda \]

    D) \[2m\lambda /nh\]

    Correct Answer: B

    Solution :

    [b] Momentum imparted per unit time =np \[\Rightarrow F=\frac{nh}{\lambda }\text{     }\therefore \text{Acceleration=}\frac{nh}{m\lambda }\]
