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

Options

  1. An ^4
  2. Bn ⁻⁴
  3. Cn ^2
  4. Dn ⁻²

Correct answer

B. n ⁻⁴

Step-by-step solution

The centripetal force of the rotating electron is given by F= m^2 r But, according to Bohr, v 1 n and r n ^2 i.e. F v ^2 r ^2 F 1 n ^2 n ^2 F 1 n ^4
