An electron is revolving in a circular orbit of radius \(r\) in a hydrogen atom. The angular momentum of the electron is L. The relation between dipole moment ( m ) associated with it, gyromagnetic ratio ( R ) and L is
- A \(m=-\frac{L}{R}\)
- B \(\mathrm{m}=-\mathrm{RL}\)
- C \(\mathrm{m}=-\mathrm{RL}^2\)
- D \(\mathrm{m}=\frac{\mathrm{R}}{\mathrm{L}}\)
Answer & Solution
Correct Answer
