In the model of hydrogen atom created by Neils Bohr, the electron moves around the lone proton in the nucleus at a speed of 2.2 x 10⁶ m/s in a circle with radius 5.3 x 10^-11 meter. Consider the orbiting electron to create a circular current loop and suppose that the proton is massive and stationary.

A) Determine the kinetic energy of the electron.

B) Find the electrostatic potential energy of the electron at this location.

C) Obtain the total energy of the electron.

D) Determine is the total energy positive. E) Obtain the magnetic field created by the electron at the location of the proton.
