NEET Physics Hydrogen Atom MCQ Question
Using the relation between orbit radius and electron velocity in a hydrogen atom, which is the correct expression for the kinetic energy of the electron in terms of the orbit radius r?
K = e^2 / (8 * π * ε₀ * r)
K = e^2 / (16 * π * ε₀ * r)
K = e^2 / (4 * π * ε₀ * r)
K = e^2 / (2 * π * ε₀ * r)
Correct Answer
Detailed Explanation
The kinetic energy of the electron is given by K = e^2 / (8 * π * ε₀ * r) as derived from the relation 2 * K = e^2 / (4 * π * ε₀ * r).
