In a hydrogen atom, the radius of `n^(th)` bohr orbit is `r_n`. The graph between log `(r_n//r_1)` and logn will beA. B. C. D.

Answer» Correct Answer - A
we know that `r_npropn^2` or `(r_n//r_1)=n^2`
So, log `(r_n//r_1)=21`ogn
Hence, the graph between log `(r_n//r_1)` and logn will be a straight line passing through origin.
The positive slope is given by `tantheta=2`.
