Q42NEET 2018Easy

Energy of the Electron & Energy Levels

The ratio of kinetic energy to the total energy of an electron in a Bohr orbit of the hydrogen atom, is

Show answer and solution

Answer: (b)

  1. KE=ke22rKE = \frac{ke^2}{2r} and E=−ke22rE = -\frac{ke^2}{2r}, so KE=−EKE = -E.
  2. So the answer is (b) 1:−11 : -1.
