Bohr Model: Orbits, Speed & Angular Momentum

The force acting on the electron in hydrogen atom (Bohr' theory) is related to the principle quantum number 'nn' as

Show answer and solution

Answer: (b)

  1. Coulomb force F=ke2r2F = \frac{ke^2}{r^2}, r∝n2r \propto n^2.
  2. F∝n−4F \propto n^{-4}
  3. So the answer is (b) n−4n^{-4}.
