The half-life of a radioactive substance is 12 minutes. The time gap between \(28 \%\) decay and \(82 \%\) decay of the radioactive substance is
- A 6 minutes
- B 18 minutes
- C 12 minutes
- D 24 minutes
Answer & Solution
Correct Answer
(D) 24 minutes
Step-by-step Solution
Detailed explanation
Given half-life \(\mathrm{T}_{1 / 2}=12\) minutes. Time gap between \(28 \%\) decay i.e., \(100-100 \times \frac{28}{100}=72\) and \(82 \%\) decay i.e., \(100-100 \times \frac{82}{100}=18\) Therefore…
