The wavelengths of electron waves in two orbits is \(3: 5\). The ratio of kinetic energy of electrons will be
- A \(25: 9\)
- B \(5: 3\)
- C \(9: 25\)
- D \(3: 5\)
Answer & Solution
Correct Answer
(A) \(25: 9\)
Step-by-step Solution
Detailed explanation
From de-Broglie's equation \(\lambda=\frac{h}{m v}\) \(\begin{aligned} \Rightarrow & \lambda^2 & =\frac{h^2}{m^2 v^2} \\ \Rightarrow & m v^2 & =\frac{h^2}{m \lambda^2}\end{aligned}\)…
