Statement-1: Half life of tritium is 12....

Statement-1: Half life of tritium is 12.5 yr. The fraction of tritium that remains after 50 yr is 6.25%
Statement-2: `N/(N_(0))=(1/2)^(n)=(1/2)^(t//T)`
`=(1/2)^(12.5//50) =1/16=6.25%`.

A

Statement-1 is true, Statement-2 is true and Statement-2 is correct explanation of Statement-1.

B

Statement-1 is true, Statement-2 is true, but Statement-2 is not a correct explanation of Statement-1.

C

Statement-1 is true, but Statement-2 is false

D

Statement-1 is false, but Statement-2 is true.

Text Solution

Verified by Experts

The correct Answer is:
A
Both the statements are true, and statement-2 is correct explanation of statement-1.
`N/(N_(0))=(1/2)^(50//12.5)=(1/2)^(4)=1/16=100/16%=6.25%`
