Dual Nature Of Light Question 351
Question: 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
Options:
A) $ m\lambda /nh $
B) $ nh/m\lambda $
C) $ nh/m\lambda $
D) $ 2m\lambda /nh $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Momentum imparted per unit time =np
$ \Rightarrow F=\frac{nh}{\lambda }\text{ }\therefore \text{Acceleration=}\frac{nh}{m\lambda } $
