Which one of the following nuclei has shorter mean life?

A

C

B

A

C

Same for all

D

B

Text Solution

Verified by Experts

The correct Answer is:
B
(b): As `(dN)/(dt)` (activity) drops sharply in case of A so disintegration constant `lamda` is high for A. Average life (Mean life) = `1/(lamda)`
So, average life will be shortest for A.
