0/3 points CHALLENGE PROBLEM - mhe 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 R0 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? O/ 1 point A long coaxial cable has a solid inner conductor with radius a and a hollow outer conductor with radius b. If the inner conductor hasp = po/r, p0 = const. and the outer conductor has 00, determine E for 'r
