A mixture consists of two radioactive materials `A_1` and `A_2` with half-lives of `20 s` and `10 s` respectively. Initially the mixture has `40 g` of `A_1` and `160 g` of `a_2`. The amount the two in the mixture will become equal after

20 s

40 s

60 s

80 s

Text Solution

Verified by Experts

The correct Answer is:

For `A, 40g overset(20s)to 20g overset(20s)to 10g`
For `B, 160g overset(10s)to 80g overset(10s)to40g overset(10s)20g overset(10s)10g`
