The variation of decay rate of two radioactive samples A and B with time is shown in figure.
Which of the following statements is true?
1
Decay constant of A is greater than that of B, hence A always decays faster than B.
2
Decay constant of B is greater than that of A but its decay rate is always smaller than that of A.
3
Decay constant of A is greater than that of B but it does not always decay faster than B.
4
Decay constant of B is greater than that of A but still its decay rate becomes equal to that of A at a later instant.
