The half life of C-14 is 5600 years. A sample of freshely cut wood from a tree contains 10 mg of C-14. The amopunt left in the sample after 50000 years is (a-x)`xx100`. The value of `(a-x)xx100` is

Text Solution

Verified by Experts

The correct Answer is:
2
`a-x=N""_(0)/2""^(n)=10/2""^(9)=10/512xx100=1.953=2,n=t/t""_(1//2)`
