1. The radius of the hydrogen atom is 0.053 nm.
(a) What is the Coulomb force between the electron and the proton in the atom?
(b) What is the centripetal acceleration of the electron orbiting the proton (assuming the proton is at rest since it is much heavier)?
(c) What is the frequency of the circular motion of the electron in the hydrogen atom? Please show work.
