The half`-` life periof of a radioactive element is 140 days. After 560 days, one gram of the element will reduce to

A

`(1)/(2)g`

B

`(1)/(4)g`

C

`(1)/(8)g`

D

`(1)/(16)g`

Text Solution

Verified by Experts

The correct Answer is:
D
`T=nxxt_(1//2)`
`:. n=(T)/(t_(1//2))=(560)/(140)=4`
Now, ` N_(t)=N_(0)((1)/(2))^(n)=1xx((1)/(2))^(4)=(1)/(16)g`
