A fraction f1 of a radioactive sample de...

A fraction `f_1` of a radioactive sample decays in one mean life, and a fraction `f_2` decays in one half life. Then

A

`X_(1) lt X_(2)`

B

`X_(1) gt X_(2)`

C

`X_(1) ge X_(2)`

D

`X_(2)=5.44 X_(1)`

Text Solution

Verified by Experts

The correct Answer is:
B
As mean life = 1.44 half-life
`rArr` Mean life `gt` half-life
`therefore X_(1) gt X_(2)`
