The ratio of the orbital dipole moment to the orbital angular moment i

1.	The ratio of the orbital dipole moment to the orbital angular moment is given by(a) e/m(b) –e/m(c) e/2m(d) –e/2mI got this question in an online quiz.This question is from Magnetic Dipole in division Magnetic Forces and Materials of Electromagnetic Theory
Answer» Right choice is (d) –e/2m To explain I would say: The ORBITAL dipole moment is GIVEN by M = 0.5 x eVangx r^2 and the orbital angular moment is given by Ma = m x Vangx r^2. Their ratio M/Ma is given by –e/2m, the negative SIGN indicates the CHARGE of electron.
