In a classical model of the hydrogen atom, the electron orbits the proton in a circular orbit of radius 0.053 What is the orbital frequency? The proton is so much more massive than the electron that you can assume the proton is at rest. Specify the units also be very clear with answer.
An electron moves in a circular path perpendicular to a constant magnetic field with a magnitude of4.50mT. The angular momentum of the electron about the center of the circle is4.00multiplied by10-25J·s. Determine the radius of the circular path
