In Bohr's model, the atomic radius of the first orbit is `r_(0)`. Then, the radius of third orbit is

A

`r_(0)/9`

B

`r_(0)`

C

`9r_(0)`

D

`3r_(0)`

Text Solution

Verified by Experts

The correct Answer is:
C

`r_(n) = r_(1)n^(2)`, where `r_(1) = r_(0)`
`therefore v_(3) = r_(0)(3)^(2) = 9r_(0)`
