A sample of a radioactive nucleus A disintegrates to another radioactive nucleus 
, which in turn disintegrates to some other stable nucleus C. Plot of a graph showing the variation of number of atoms of nucleus 
vesus time is :
(Assume that at 
, there are no 
atoms in the sample)
Text Solution
Verified by ExpertsB
(stable)
Initially no. of atoms of 
after 
, no. of atoms of 
will starts increasing & reaches maximum value when rate of decay of 
rate of formation of B. After that maximum value, no. of atoms will starts decreasing as growth 
decay both are exponential functions, so best possible graph is
