In the Bohr model of the hydrogen atom, in the lowest energy state the electron revolves round the proton at a speed of `2.2 xx 10^6 m/s` in a circular orbit of radius `5.3 xx 10^-11` m.
(a) What is the orbital period of the electron?
(b) If the orbiting electron is considered to be a current loop, what is the current I? (c) What is the magnetic moment of the atom due to the motion of the electron?
