Question
Two radioactive sources A and B initially contain equal number of radioactive atoms. Source A has a half-life of 1 hour and source B has a half-life of 2 hours. At the end of 2 hours, the ratio of the rate of disintegration of A to that of B is :
Options
A.1 : 2
B.2 : 1
C.1 : 1
D.1 : 4
Solution
No. of atoms of A after 2hrs. = 
No of atoms of B after 2hrs. =
= 1
No of atoms of B after 2hrs. =
= 1Create a free account to view solution
