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?

In this problem, we will go through the famous experiment led by Robert A. Millikan. The charge of the electron that he calculated by this experiment is 0.6% off from the currently accepted value, that too due to the imprecise value of viscosity of air known at the time. This experiment demonstrates that the electric charge of the oil droplet is some integer multiple of electron charge - thereby establishing charge quantization as an experimental fact. It's a free-body diagram. Here, we depict an oil droplet that is falling downwards due to gravity in an air medium. The droplet experiences an upward force due to air friction. When the two forces are on the droplet balance, the droplet falls steadily with velocity vd. Find the friction coefficient k. Given the symbolic expression for the mass of the oil droplet m, acceleration due to gravity g, downward terminal velocity of the droplet vd.
