Question
A radioactive martial of half T was produced in a nuclear in a nuclear reactor at different instants. The quantity produced second time twice of that produced first time. If now their present activities are A1 and A2 respectively then their difference equals
Options
A.
B.
C.
D.
Solution
A1 = λ Ne-λt1, A2 = 2NλNe-λt2
⇒
e-λ(t1 -t2) ⇒ ln 
= - λᐃt ⇒ ᐃt = 
⇒
e-λ(t1 -t2) ⇒ ln = - λᐃt ⇒ ᐃt = Create a free account to view solution
