The ratio of total energy to the kinetic energy of an electron in a Bohr orbit of the hydrogen atom is
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → -1 : 1
In Bohr model:
Kinetic energy of electron: $K = -E$
Total energy of electron: $E = -K$
Potential energy: $U = 2E = -2K$
Therefore, $\frac{E}{K} = \frac{-K}{K} = -1$
Answer: The ratio of total energy to kinetic energy is $-1$.
