In the lowest energy state of the hydrogen atom, the most probable distance of the single electron from the central proton (the nucleus) is 5.2 x 10-11m.

(a) Compute the magnitude of the proton's electric field at that distance. The component μ s, z

of the proton's spin magnetic dipole moment measured on a z axis is 1.4 x 10-26 J/T.

(b) Compute the magnitude of the proton's magnetic field at the distance 5.2 x 10-1l m on the z axis.

(c) What is the ratio of the spin magnetic dipole moment of the electron to that of the proton?
