`C^(14)` has half-life 5700 year. 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)= N_(0) ((1)/(2)) ^(2) = 0.25 N _(0)`
