According to Bohr's principle, which is ...

According to Bohr's principle, which is the correct relation between principle quantum number (n) and radius of orbit (r ) ?

A

`rpropn`

B

`rpropn^(2)`

C

`rprop1/n`

D

`rprop1/n^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
Bohr suggested a formulae to calculate the radius and energy of each orbit and gave the following formulae
`r_(n)=(n^(2)h^(2))/(4pi^(2)kme^(4)Z)`
Where except `n^(2)`, all other unit are constant so `r_(n)propn^(2)`.
