Consider a hypothetical case of a radinuclide A which produces a daughter B which is turn decays to a stable product C. the half life of B is 5 times that of A. take initial population of both B and C to be zero. (a) Using qualitative arguments only, plot the variation of population of A,B and C with time. (b) Find the ratio of population of B to that of A at the instant the population of B becomes maximum. (c) Describe qualitatively how the slope of the graph of population oc C changes with time. |

Answer» (b) `(N_(B))/(N_(A))=5` (C) The slope FIRST INCREASES. It becomes maximum when `N_(B)` is maximum. Thereafter the slope decreases. |
