Question

An electron in a Hydrogen atom moves around in a circular orbit of radius 0.52 x 10^-10 m. Suppose the hydrogen atom is transported into a magnetic field of 0.70 T, where the magnetic field is parallel to the orbital angular momentum.

a) At what frequency does the electron revolve in the magnetic field?

a) An electron in a Hydrogen atom moves around in a circular orbit of radius 0.52 x 10-10 m. Suppose the hydrogen atom is transported into a magnetic field of 0.70 T, where the magnetic field is parallel to the orbital angular momentum. At what frequency does the electron revolve in the magnetic field?

b) What is the associated speed of the electron? Assume that the radius of the orbit remains constant.

c) Imagine the electron is initially traveling at a speed of 2.20 x 106 m/s, what is the change in the kinetic energy of the electron when it is introduced in the magnetic field?
