Half-life period of a given radioactive ...

Half-life period of a given radioactive sample is `tau` . Its average life would be

A

`tau` In 2

B

`tau` / In 2

C

1 / `tau`

D

In 2 / `tau`

Text Solution

Verified by Experts

The correct Answer is:
B
The relation between half-life `(T_(1//2))` and mean-life (`tau`) is
`tau` = 1.44 `T_(1//2)` or `T_(1//2)` = `tau`/ In 2
