Some of the earliest atomic models held that the orbital velocityof an electron in an atom could be correlated with the radius ofthe atom. Assume that the radius of the hydrogen atom is 7.51·10-11m and that the electrostatic force is responsible for the circularmotion of the electron.

a) What is the electron's orbital velocity?

b) What is the kinetic energy of this orbital electron in eV?
