Samples of two radioactive nuclides A and B are taken. λA and λB are the disintegration constants of A and B respectively. In which of the following cases, the two samples can simultaneously have the same decay rate at any time?
- Initial rate of decay of A is twice the initial rate of decay of B and lA = lB.
- Initial rate of decay of A is twice the initial rate of decay of B and lA > lB.
- Initial rate of decay of B is twice the initial rate of decay of A and lA > lB.
- Initial rate of decay of B is twice the initial rate of decay of A at t = 2h and lB = lA.
Answer
(B) Initial rate of decay of A is twice the initial rate of decay of B and l A > l B .
