If the radius of the $3 rd$ Bohr's orbit of hydrogen atom is $r_{3}$ and the radius of $4^{th}$ Bohr's orbit is $r_{4}$ . Then:

Options:

Answer:

Solution:

$r = 0.529 \times \frac{n ^{2}}{Z} \overset{˚}{A} r_{3} = 0.529 \times \frac{3 ^{2}}{1} \Rightarrow r_{4} = 0.529 \times \frac{4 ^{2}}{1} \frac{r _{4}}{r _{3}} = \frac{4 ^{2}}{3 ^{2}} = \frac{16}{9} \Rightarrow r_{4} = \frac{16 r _{3}}{9}$
