A) 5 sec
B) 10 sec
C) 20 sec
D) 30 sec
Correct Answer: B
Solution :
\[A={{A}_{0}}{{\left( \frac{1}{2} \right)}^{\frac{t}{{{T}_{1/2}}}}}\Rightarrow \frac{1}{64}={{\left( \frac{1}{2} \right)}^{\frac{60}{{{T}_{1/2}}}}}\] \[\Rightarrow {{\left( \frac{1}{2} \right)}^{6}}={{\left( \frac{1}{2} \right)}^{\frac{60}{{{T}_{1/2}}}}}\Rightarrow {{T}_{1/2}}=10\sec \]You need to login to perform this action.
