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
