Question
A radioactive nucleus is being produced at a constant rate $\alpha$ per second. Its decay constant is $\lambda $. If $N_0$ are the number of nuclei at time $t = 0$, then maximum number of nuclei possible are
✓
Answer
(a) Maximum number of nuclei will be present when rate of decay = rate of formation
==> $\lambda N = \alpha $
==> $N = \frac{\alpha }{\lambda }$
