A) 200
B) 150
C) 400
D) 360
Correct Answer: A
Solution :
\[{{A}_{0}}=1600\text{ }cps\] at \[t=8\text{ }second\] \[100=\frac{1600}{{{2}^{n}}}\] \[{{2}^{n}}\,=\,16\,=\,{{2}^{4}}\] \[n=4\,=\,\frac{8}{{{T}_{1/2}}}\] \[{{T}_{1/2}}\text{ }2\] second In \[t=6\] sec number of half life?s = 3 \[\therefore \,\,\,\,A\,=\,\frac{1600}{{{2}^{3}}}\,=\,200\,cps\]You need to login to perform this action.
