Bohr Model: Orbits, Speed & Angular Momentum

The angular momentum of the electron in the third Bohr orbit of hydrogen atom is ' ll '. Its angular momentum in the fourth Bohr orbit is

Show answer and solution

Answer: (b)

  1. L=nh2π⇒L∝nL = \dfrac{nh}{2\pi} \Rightarrow L \propto n.
  2. L4L3=43⇒L4=43l\dfrac{L_4}{L_3} = \dfrac{4}{3} \Rightarrow L_4 = \dfrac{4}{3}l.
  3. So the answer is (b).
