31. In example 23 of the 6th exercise the Coulomb force acting on an electron in a distance r = 0.529x10-10 m to a proton (corresponds to the radius of a hydrogen atom) was calculated. a) What is the electric field and electric potential at this distance (reference potential = 0 V for infinite distance)? What is the electric potential energy of an electron at this distance? b) What is the kinetic energy (in eV) of an electron which moves on a circular orbit with that radius around the proton? What is the ionisation energy (in eV) of the hydrogen atom (energy which is needed to remove the electron fully from the proton)?
