The total energy of an electron in an orbit of hydrogen atom is E. The potential energy of the electron in the same orbit is

Options

  1. AE
  2. BE 2
  3. C2 E
  4. D3 E

Correct answer

C. 2 E

Step-by-step solution

Kinetic energy is given by K . E = KZe ^2 2 r Potential energy is given by P.E =- K^2 e^2 r Total energy = K E + P . E E = KZe ^2 2 r - KZe ^2 r aligned & E= -K Z e^2 2 r & E= P E 2 & P . E=2 E aligned
