The ratio of the magnitude of the kinetic energy to the potential energy of an electron in the 5th{5}^{\text{th}} excited state of a hydrogen atom is :

Options

  1. A44
  2. B14\dfrac{1}{4}
  3. C12\dfrac{1}{2}
  4. D11

Correct answer

C. 12\dfrac{1}{2}

Step-by-step solution

As we know, KE=12∣PE∣KE = \dfrac{1}{2} | PE | for any orbit.

∴KE∣PE∣=12∴ \dfrac{KE}{| PE |} = \dfrac{1}{2}
