What is ratio of Bohr magneton to the nuclear magneton?

Options

  1. Am_p / m_e
  2. Bm_p^2 / m_e^2
  3. C1
  4. Dm_e m_p

Correct answer

A. m_p / m_e

Step-by-step solution

Magnetic moment associated with electrons orbitting around the nucleus is given in terms of Bohr magneton ( _B ) _B= e 2 m_e e= electronic charge, m_e= electronic mass. In nuclear physics, magnetic moments associated with the spins of protons and neutrons are expressed in nuclear magnetons ( _N ) _N= e 2 m_p aligned & m_p= mass of a proton. & _B _N = m_p m_e aligned
