There are two radionuclei \( \mathrm{A} \) and \( \mathrm{B} \). \( \mathrm{A} \) is an alpha emitter and \( \mathrm{B} \) is a beta emitter. Their distintegration constants are in the ratio of \( 1: 2 \). What should be the ratio of number of atoms of A \& B at time
\( \mathrm{P} \) \( t=0 \) so that probabilities of getting \( \alpha \) and \( \beta \) particles are same at time \( t=0 \).
(A) \( 2: 1 \)
(B) \( 1: 2 \)
(C) e
(D) \( \mathrm{e}^{-1} \)
