If n(t) number of radioatoms are present...

If `n_(t)` number of radioatoms are present at time `t`, the following expression will be a constant

A

`n_(t)//t`

B

ln `n_(t)//t`

C

`d ln n_(t)//dt`

D

`t.n_(t)`

Text Solution

Verified by Experts

The correct Answer is:
C
`- (dn_(t))/(dt) = lamda n_(t) rArr - (1)/(n_(1)) (dn_(t))/(dt) = lamda`
`rArr (d)/(dt) (ln, n_(t)) = - lamda`, a constant
