MCQPhysics

NCERT · Class 12 · Physics · AtomsIn the Bohr model of a hydrogen atom, what is the radius of the nth orbit proportional to?

Step-by-Step Solution

The radius of the nth orbit in the Bohr model is given by r_n = (4πε₀ n² h²) / (m e² Z), which shows that the radius is directly proportional to the square of the principal quantum number (n²).
