Nuclear Physics and RadioactivityHard
Question
Two radioactive martial A1 and A2 have decay constants of 10λ0 and λ0. If initially they have same number of nuclei, the ratio of number of their undecided will be (1/e) after a time
Options
A.
B.
C.
D.1
Solution
N = N0e-λ0t, N′ = N0e-10λ0t ⇒ 
e-9λ0t
⇒ t =
e-9λ0t⇒ t =
