A) \[\lambda {{N}^{2}}\]
B) \[\lambda N\]
C) \[\frac{\lambda }{N}\]
D) \[{{\lambda }^{2}}N\]
Correct Answer: B
Solution :
At any instant the rate of decay of radioactive atoms is proportional to the number of atoms present at that instant ie, \[-\frac{dN}{dt}\propto N\] or \[-\frac{dN}{dt}=R=\lambda N\] where \[\lambda \] is decay constant,You need to login to perform this action.
