A radioactive sample decays by \( \beta \)-emission. In first
\( \mathrm{P} \)
two seconds ' \( n \) ' \( \beta \)-particles are emitted and in next 2
W
seconds, '0.25 n' \( \beta \)-particles are emitted. The half-life of radioactive nuclei is:
(1) \( 2 \mathrm{sec} \)
(2) \( 4 \mathrm{sec} \)
(3) \( 1 \mathrm{sec} \)
(4) none of these
