Let \(R _1\) be the radius of the second stationary orbit and \(R_2\) be the radius of the fourth stationary orbit of an electron in Bohr's model. The ratio \(\frac{ R _1}{ R _2}\) is
- A \(0.25\)
- B \(0.5\)
- C \(2\)
- D \(4\)
Answer & Solution
Correct Answer
(A) \(0.25\)
Step-by-step Solution
Detailed explanation
\(R ( n )=0.529 \frac{ n ^2}{ z }\) \(\frac{ R _1( n =2)}{ R _2( n =4)}=\frac{2^2}{4^2}=\frac{1}{4}=0.25\)
