Question
Starting with a simple of pure 66Cu, 
of it decays in to Zn in 15 minutes. The corresponding half life is
of it decays in to Zn in 15 minutes. The corresponding half life isOptions
A.15 minutes
B.10 minutes
C.7
minutes
minutesD.5 minutes
Solution
days of Cu decays.∴ Cu undecayed, N = 1 -
∴ No. Of half life = 3
⇒ half life period, T =
= 5 minutesCreate a free account to view solution
