A) \[\frac{1}{4}\]
B) \[\frac{1}{2\sqrt{2}}\]
C) \[\frac{1}{\sqrt{2}}\]
D) \[\sqrt{2}-1\]
Correct Answer: C
Solution :
According to radioactive decay, \[\frac{N}{{{N}_{0}}}={{\left( \frac{1}{2} \right)}^{t/{{T}_{1/2}}}}\] According to question, \[t=\frac{{{T}_{1/2}}}{2}\] Then, \[\frac{N}{{{N}_{0}}}={{\left( \frac{1}{2} \right)}^{1/2}}=\frac{1}{\sqrt{2}}\]You need to login to perform this action.
