There are n number of radioactive nuclei in a sample that undergoes beta decay. If from the sample, `n'` number of `beta`-particels are emitted every `2s`, then half-life of nuclei is .

Options

A. `n'//2`
B. `0.693 xx(2n//n')`
C. `0.693 1n(2n//n')`
D. `0.693 xx(n//n')`

Answer

b

Explanation

`t_(1//2) =(0.693)/(lambda)` .
