Goal:The intent of this problem is to understand how electrostatic models can be used outside of electrical engineering. This basic model is used to understand chemical reactions, bonding, and other forms of atomic processes. It also shows you the strength of electrostatic forces in an atom. The Thomson model of a hydrogen atom is a sphere of positive charge with radius Ro with an electron (a point charge) at its center. The total positive charge equals the electronic charge q. What is the force of attraction between an electron at a distance R from the center of the sphere of positive charge? OOOO qR 4π€, Ro O q²R 3πEO q²R 4π€, Ro
