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`]
