Problem

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 \times 10^6 \text{ m/s}

in a circular orbit of radius

5.3 \times 10^{-11} \text{ 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?
