A) \[E/c\]
B) \[2E/c\]
C) \[Ec\]
D) \[E/{{c}^{2}}\]
Correct Answer: B
Solution :
[b] Initial momentum of surface |
where c = velocity of light (constant). |
Since, the surface is perfectly reflecting, so the same momentum will be reflected completely. |
Final momentum, |
(with negative value) |
Change in momentum |
Thus, momentum transferred to the surface is |
