Determine the number of nuclei that will be decayed upto one average life of radioactive material? (

{N_0}

: Initial number of nuclei)

View answer and explanation

Correct option: B

{N_0}\left( {1 - \frac{1}{e}} \right)

Option B is correct because the number of nuclei decayed up to one average life is given by the formula

N_0(1 - e^{-t/\tau})

, where

\tau

is the average life.
