A) \[\frac{1}{16}\]
B) \[\frac{1}{4}\]
C) \[\frac{1}{8}\]
D) \[\frac{1}{2}\]
Correct Answer: D
Solution :
Given, half-life period = 1600 min Total time = 6400 min Number of life \[(n)=\frac{Total\text{ }time}{Half-life\text{ }period}\] \[=\frac{6400}{1600}=4\] Amount left\[=\frac{1}{{{2}^{n}}}=\frac{1}{{{2}^{4}}}=\frac{1}{16}\]You need to login to perform this action.
