The ratio of radii of the first three Bohr orbits of H-atom is :

A

`1:2:3`

B

`1:4:9`

C

`1:3:27`

D

`1:sqrt(2):sqrt(3)`

Text Solution

Verified by Experts

The correct Answer is:
B

`r_(n)=0.059n^(2)`
`r_(1)=0.059, r_(2)=0.059xx4,r_(3)=0.059xx9`
`:.r_(1):r_(2):r_(3)=1:4:9`

The gravitational attraction between electron and proton in a hydrogen atom is weaker than the coulomb attraction by a factor of about 10^(-40) . An alternative way of looking at this fact is to estimate the radius of the first Bohr orbit of a hydrogen atom if the electron and proton were bound by gravitational attraction.
