A radioactive nucleus 
has 3 times the decay constant as compared to the decay constant of another radioactive nucleus 
. If initial number of both nuclei are the same, what is the ratio of number of nuclei of 
to the number of nuclei of 
, after one half-life of 
?

Text Solution
Verified by ExpertsThe correct answer is:
D
Given 
we know, 
after 1 half life of 
, No of nuclei 
1 half life of 
half life of 
∴ after 
of 
, no. of nuclei 
ratio of 
to
