Bohr Model: Orbits, Speed & Angular Momentum

The angular momentum of an electron in a hydrogen atom is proportional to: (Where rr is the radius of orbit of electron)

Show answer and solution

Answer: (c)

  1. L=nh2π∝nL = \frac{nh}{2\pi} \propto n
  2. r∝n2⇒n∝rr \propto n^2 \Rightarrow n \propto \sqrt{r}
  3. So L∝rL \propto \sqrt{r}, answer (c).
