A) \[\frac{n}{N}s\]
B) \[\frac{N}{n}s\]
C) \[\frac{0.693N}{n}s\]
D) \[\frac{0.693n}{N}s\]
Correct Answer: C
Solution :
\[\frac{dN}{dt}=-\lambda N\] \[\Rightarrow \] \[n=-\lambda N\] \[\lambda =-\frac{n}{N}\] \[\therefore \] Half - life \[=\frac{0.693}{\lambda }\] \[=\frac{0.693\,N}{n}\]You need to login to perform this action.
