Question
there are two radio nuclei A and B. A is α-emitter and B is a β-emitter, their decay constant are in the ratio 1:2. what should be the no. of atoms of A&B at time t=0, so that probability of getting α and β-particles are same at time t=0
(a) 2:1
(b) 1;2
(c) 1:4
(d) 4:1
Joshi sir comment
its (b)
decay constant ratio = 1:2
so half life ratio = 2:1
so for getting probability of finding alpha and beta same ratio will be 1:2
