Question

The variation of decay rate of two radioactive samples A and B with time is shown in figure

Which of the following statements is/are true?

• A. Decay constant of A is greater than that of B hence A always decays faster than B.
• B. Decay constant of A is greater than that of B, but it does not always decays faster than B
• C. Decay constant of B is smaller than that of A but still its decay rate becomes equal to that of A at a later instant.
• D. Both (2) and (3)

Answer 1

Answer: (D)

Both (2) and (3)

Answer 2
