1.	What is the half-time of a radioactive sample (in minutes), if its mean life is 200 s?(a) 0.69 min(b) 2 min(c) 2.57 min(d) 2.31 minI had been asked this question during an interview.My doubt is from Nucleus topic in section Nucleus of Physics – Class 12
Answer» The CORRECT ANSWER is (d) 2.31 min Explanation: T1/2 = 0.693t T1/2 = 0.693 × 200s T1/2 = \(\FRAC {138.6}{60}\) min T1/2 = 2.31 MINUTES
