Bohr Model: Orbits, Speed & Angular Momentum

The radius of third stationary orbit of electron for Bohr's atom is R. The radius of fourth stationary orbit will be:

Show answer and solution

Answer: (b)

Bohr radius $r_n \propto n^2$ (same atom).
$\frac{r_4}{r_3} = \frac{4^2}{3^2} = \frac{16}{9}$
So the answer is (b) $\frac{16}{9}R$ .
