Thomson’s Model of the Atom, Continued. Using Thomson’s (outdated) model of (he atom described in Problem 22.50, consider an atom consisting of two electrons, each of charge − e , embedded in a sphere of charge +2 e and radius R . In equilibrium, each electron is a distance d from the center of the atom ( Fig. P22.51 ). Find the distanced in terms of the other properties of the atom. Figure P22.51

If an electric dipole is formed by polarizing a Hydrogen atom so that the electron and proton have an effective separation of 0.05 nm, what electric field strength does the dipole generate a distance of 20 nm away, along the axis of the dipole moment? Answer in N/C.
A hydrogen atom can be considered as having a central pointlike proton of positive charge e and an electron of negative charge -e that is distributed about the proton according to the volume charge density r = A exp(-2r/a0). Here A is a constant, a0 = 0.53 *10-10 m, and r is the distance from the center of the atom. (a) Using the fact that the hydrogen is electrically neutral, find A. Then find the (b) magnitude and (c) direction of the atom’s electric field at a0.
An old model of a hydrogen atom has the charge +e of the proton uniformly distributed over a sphere of radius a0, with the electron of charge -e and mass m at its center. (a) What would then be the force on the electron if it were displaced from the center by a distance r # a0? (b) What would be the angular frequency of oscillation of the electron about the center of the atom once the electron was released?
