4. (Problems on Shell Theorems) Assume the following model of the proton. It consists of: 1) a solid spherical core having a radius 1/10 the radius of the proton; 2) a concentric hollow spherical shell with no charge; and 3) a concentric solid spherical shell which has an inner radius exactly 1/2 the radius of the proton, and an outer radius that of the radius of the proton. (The hollow spherical shell is situated in between the solid spherical core and the shell.) Assume the charge of the core is exactly half of the total charge of the proton and that charge is distributed uniformly on both the core and the solid spherical shell. What is the force (in Newtons) due to the proton on a small object having a charge equal to the charge of the electron and which is at the following distance from the center of the proton: a) exactly two proton radii; b) 1/2 the radius of the proton; c) at the surface of the core; d) zero (i.e. at the center of the proton).

Astronomers have recently discovered a new planet in a faraway solar system with a radius of roughly 395 km.395 km. Spectroscopic results indicate that the atmosphere, whose height is much smaller than the planet's radius, is largely argon, making the discovery truly controversial. Experts have deduced that argon is unlikely to be generated from the planet itself, therefore it is assumed that the argon in the atmosphere was created at the inception of the planet and is completely contained by its gravitational attraction. However, wide disagreement abounds about the composition of the planet. The surface of the planet is clearly composed of aluminum oxide, but some astronomers claim that this aluminum oxide is only a thin crust and that the planet is mostly iron. Given that the atmospheric temperature is 512 ∘C,512 ∘C, calculate the minimum density ?ρ of the planet so that its atmosphere could contain argon atoms. The molar mass of argon is 39.948 g/mol39.948 g/mol and the…
