`C^(14)` has a half life of 5700 yrs. At the end of 11400 years, the actual amount left is

A

0.5 of original amount

B

0.25 of original amount

C

0.125 of original amount

D

0.0625 of original amount

Text Solution

Verified by Experts

The correct Answer is:
B
`N=N_(0)xx((1)/(2))^(11400//5700)(thereforeT_(1//2)=5700 yr and T=11400 yr)`
`=N_(0)((1)/(2))^(2)=0.25N_(0)`
