Question

In Bohr's model of the hydrogen atom, let R, V, T and E represent the radius of the orbit, speed of the electron, time period of revolution of electron and the total energy of the electron respectively. The quantity proportional to the quantum number n is –

• A. VR
• B. RE
• C. $\frac{E}{V}$
• D. None of these

Answer 1

Answer: (A)

VR

Answer 2

R µ n², V µ $\frac{1}{n}$, T µ $\frac{R}{V}$ µ n, E µ 1/n²

(A) $V R = n$ (2) RE µ n⁰ (3) $\frac{E}{V}$ µ 1/n
