\beta

-emission. In first two seconds '

n

\beta

-particles are emitted and in next 2 seconds, '

0.25n

\beta

-particles are emitted. The half-life of radioactive nuclei is:

View answer and explanation

Correct option: C

1 \mathrm{~sec}

The correct answer is C (

1 \mathrm{~sec}

) because the half-life can be determined by analyzing the decay rates over the given time intervals using the properties of exponential decay.
