Question:

Thomson's Model of the Atom Continued. Using Thomson's (outdated) model of the atom described in Problem 22.52, consider an atom consisting of two electrons, each of charge -e, embedded in a sphere of charge + 2e and radius R. In equilibrium, each electron is a distance d from the center of the atom (Fig). Find the distance d in terms of the other properties of the atom.

+2e R.
