A) \[\frac{2I}{c}\]
B) \[\frac{I}{c}r\]
C) \[\frac{I}{c}\left( I+r \right)\]
D) \[\frac{I}{c}\left( I-r \right)\]
Correct Answer: C
Solution :
[c] \[F=\frac{dP}{dt}=\left( \frac{IA}{hc/\lambda } \right)\left( 1+r \right)\frac{h}{\lambda }\] \[\Rightarrow P=\frac{F}{A}=\frac{I}{c}\left( 1+r \right)\]You need to login to perform this action.
