Asked by Kathryn
Under the influence of the electric force of attraction, the electron in a hydrogen atom orbits around the proton on a circle of radius 5.3 x 10^-11 m. What is the orbital speed? What is the orbital period?

The centripetal force m V^2/r must equal the Coulomb attraction force ke^2/r^2.
Solve for v, the orbital speed.
The period will be
P = 2 pi r/ V
Solve for v, the orbital speed.
The period will be
P = 2 pi r/ V
