In the model of hydrogen atom created by Niels Bohr, the electron moves around the lone proton in the nucleus at a speed of 2.2 x106 m/s in a circle with radius 5.3 x 10-11meter. Consider the orbiting electron to be a small current loop, suppose that the proton is stationary and massive.
A) Obtain what is the kinetic energy of the electron?
B) Obtain the electrostatic potential energy of the electron at this location?
