A single electron is trapped in a potential box of typical size 150 nm. Estimate the electrostatic charging energy required to add a second electron to the box. Compare this energy with the typical single-particle level splitting in the box. How do your results depend on the relative dielectric constant of the material in which the box is realized?

Consider a model of an electron as a hollow sphere with radius R and the electron charge -e spread uniformly over that surface. d. Use Einstein’s equation relating rest mass to energy to derive a value for R. Unfortunately, your answer will be model-dependent. The traditional “Classical radius of the electron” is derived by setting the electrostatic work to be e2/(4pi e0 R)
Consider an oil droplet of mass mmm and charge q. We want to determine the charge on the droplet in a Millikan-type experiment. We will do this in several steps. Assume, for simplicity, that the charge is positive and that the electric field between the plates points upward. a. An electric field is established by applying a potential difference to the plates. It is found that a field of strength E0 will cause the droplet to be suspended motionless. Write an expression for the droplet's charge q. Let g be the acceleration due to gravity. Express answer in terms of the suspending field E0 and the droplet's weight mg. b. Determine the mass of a microscopic droplet. Consider a mass m falling through a viscous medium in which there is a retarding or drag force. For very small particles, the retarding force is given by Fdrag =−bv, where b is a constant and v is the droplet's speed. The negative sign tells us that the drag force vector points upward when the droplet is falling. A falling…
