Nuclear Physics and RadioactivityHard
Question
The half-life period of a radio-active element X is same as the mean life time of another radioactive element Y. Initially they have the same number of atoms. Then
Options
A.X will decay faster than Y
B.Y will decay faster than X
C.X and Y have same decay rate initially
D.X and Y decay at same rate always.
Solution
t1/2 = 
tmean =
= - λN
⇒ λx = λy(0.6932) ⇒ λy > λx
tmean =
= - λN ⇒ λx = λy(0.6932) ⇒ λy > λxCreate a free account to view solution
