A) \[\sqrt{2}\]
B) \[\frac{1}{\sqrt{2}}\]
C) \[\frac{\sqrt{2-1}}{\sqrt{2}}\]
D) \[\frac{1}{2}\]
Correct Answer: B
Solution :
Undecased fraction \[\frac{N}{{{N}_{0}}}={{\left( \frac{1}{2} \right)}^{n}}\] Where,\[n=No\]of half lives\[\frac{N}{{{N}_{o}}}={{\left( \frac{1}{2} \right)}^{\frac{T}{{{T}_{1/2}}}}}\Rightarrow \frac{N}{{{N}_{0}}}={{\left( \frac{1}{2} \right)}^{\frac{2}{4}}}={{\left( \frac{1}{2} \right)}^{\frac{1}{2}}}=\frac{1}{\sqrt{2}}\]
