A rock sample has radioactive isotope A that decays into a stable product B. half life of A is 10^(3) year. It was found that the rock sample contained n_(1) moles of A and (n_(1))/(4) moles of b. Plot the variation of population of B with time. After how much time the rock will have equal population of A and B? [Given 2.^(0.68)=1.6 ]
