The ratio of kinetic energy to the total energy of an electron in a Bohr orbit of the hydrogen atom, is
  1. A
    1 : 1
  2. B
    1 : -1
  3. C
    2 : -1
  4. D
    1 : -2
View written solutionFree

Correct answer: B

In a Bohr orbit of the hydrogen atom,

Kinetic energy = – (Total energy)

So, Kinetic energy : Total energy = 1 : –1
