Two radioactive substances \(A\) and \(B\) have decay constants \(5 \lambda\) and \(\lambda\) respectively. At \(t=0\), a sample has the same number of the two nuclei. The time taken for the ratio of the number of nuclei to become \(\left(\frac{1}{a}\right)^2\) will be: 📲PW App Link - https://bit.ly/YTAI_PWAP 🌐PW Website - https://www.pw.live
