In the Bohr model of the hydrogen atom, ...

In the Bohr model of the hydrogen atom, let R, v and E represent the radius of the orbit, the speed of electron and the total energy of the electron respectively. Which of the following quantity is proportional to the equantum number n

A

vr

B

rE

C

`(r)/(E )`

D

`(r)/(v)`

Text Solution

Verified by Experts

The correct Answer is:
A
According to Bohr theory of hydrogen atom, `r prop n^(2)`
`v prop (1)/(n)`
`E prop (1)/(n^(2)) therefore vr prop n`
