In the Bohr's model of hydrogen atom, the ratio of the kinetic energy to the total energy of the electron in `n^(th)` quantum state is:

Options

A. 1
B. `-1`
C. 2
D. `1//2`

Answer

B

Explanation

Total energy is sum of the potential energy and kinetic energy
T.E. = -2K + K=-K
where K is kinetic energy and -2K is potential energy.
`therefore` ratio of total energy of electron to kinetic energy is `(-K)/K=-1`
