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