In Bohr's model, if the atomic radius of the first orbit is `r_(0)`, then the radius of the fourth orbit is

A

`r_(0)`

B

`4r_(0)`

C

`r_(0)//16`

D

`16 r_(0)`

Text Solution

Verified by Experts

The correct Answer is:
D
`r_(n) prop n^(2) rArr (r_(4))/(r_(1)) = ((4)/(1))^(2) = (16)/(1) rArr r_(4) = 16 r_(1) rArr r_(4) = 16 r_(0)`
