If \(75 \%\) of a radioactive sample disintegrates in 16 days, the half-life of the radioactive sample is
- A 6
- B 4 days
- C 8
- D 12
Answer & Solution
Correct Answer
(C) 8
Step-by-step Solution
Detailed explanation
If \(N_0\) be the initial amount of radioactive sample, then after \(t=16\) day, remaining amount, \(\begin{aligned} N & =N_0-75 \% \text { of } N_0 \\ & =N_0-\frac{75}{100} N_0=\frac{N_0}{4} \end{aligned}\) Since, we know that,…
