(a) How would you place two electrons on a sphere of radius R so that the electrostatic potential energy is minimized. How would you place three electrons to solve the same problem.

(b) Explain in physical terms how a microwave oven works. What would happen when you put a conductor in the microwave oven? Explain.

Expert Solution

I put a 1/4 inch thick clear glass container into the microwave with a plate on top and put it in for almost 5 minutes (there was lots of soup). When It came out the soup was really hot but I could still hold the top parts of the container. After measuring the soup's heat it was about 120-130 degrees but the top part felt cool to the touch

Microwave ovens deliver heat to things that are electrically conductive, like water that has stuff dissolved in it, which is almost all water. Glass is an insulator, so it doesn't get heated (by the microwaves, it may get heated by the soup). Never put metal objects in a microwave

A solid sphere of radius R, a solid cylinder of radius R, and a hollow cylinder of radius R all have the same mass, and all three are rotating with the same angular velocity. The sphere is rotating around an axis through its center, and each cylinder is rotating around its symmetry axis. Which one has the greatest rotational kinetic energy? both cylinders have the same rotational kinetic energy the solid cylinder the solid sphere they all have the same...

A wheeled cart (frictionless), a solid cylinder of radius r, a solid sphere of radius r, and a hollow cylinder of radius r are all allowed to roll down an incline. Derive a general relationship for the linear acceleration of each object depending on the angle of the ramp and the rotational inertia. You may assume that the frictional force is small enough that it is only causing rotation in each case.

A non-conducting sphere of radius R centered at O contains a spherical cavity of radius R’ centered at O'. Let d be the displacement of O’relative to 0. Throughout the sphere, there is a uniform charge density rho_0 (except inside the cavity, which is uncharged). (a) Use the principle of superposition to write down an expression for E(r) everywhere. (b) Repeat (a) for the electric potential b(r).
