The radius of third stationary orbit of electron for Bohr's atom is \(R\). The radius of fourth stationary orbit will be what?
- A \(\frac{4}{3} R\)
- B \(\frac{16}{9} R\)
- C \(\frac{3}{4} R\)
- D \(\frac{9}{16} R\)
Answer & Solution
Correct Answer
(B) \(\frac{16}{9} R\)
Step-by-step Solution
Detailed explanation
\(r \propto \frac{n^2}{Z}\) \(\frac{r_4}{r_3}=\frac{4^2}{3^2}\) \(r_4=\frac{16}{9} R\)
