If, in a hydrogen atom, radius of nth Bohr orbit is `r_(n)` frequency of revolution of electron in nth orbit is `f_(n)` and area enclosed by the nth orbit is `A_(n)` , then which of the pollowing graphs are correct?

Options

A. a,b
B. a,b,c
C. a,b,c,d
D. None of these

Answer

B

Explanation

`A_(n) = n^(4)A`
`log.(A_(n))/(A) = 4 log n`
`r_(n) = n^(2)r`
In `(r_(n))/(r) = 2 logn`
