The electron of mass m = 9.1 × 10-31 kg and of charge –e where e = + 1.6 × 10–19 C performs uniform circular motion around the Hydrogen nucleus of charge +e. Let r = 5.3 × 10-11 m be the orbital radius of the electron, and v = 2.2 × 106 m\s the orbital speed, then the gyromagnetic ratio of this electron is
