I am referring to the voltage gradient outside of the solid cylinder. I need to know how to remove the charge term or replace it with a numerical value.

Hello, I am a bit trumped. I know how to calculate the voltage of a single uniform cylinder: V(r) = (-q/2 Pi ep0) Ln(r/R0) + V0 q: Charge density r: radius from outside of the cylinder. r >= R0 R0: radius of the uniform cylinder V0: applied voltage to the cylinder Here is my...

A friend and I were debating the solution to this problem, seen below, and cannot solve it without using Lagrange equations but it is suppose to have a solution that is super simple; but we didn't see it. Anyway, it is a old qualifier question from the Univ. of Wisconsin (open record so...

Hello, I am stuck on the coriolis force. If an object is dropped how do I get the eastward deflection when looking from an inertial frame? I know how from the rotating frame but for some reason I am stuck, i.e. what terms to use. Also, if I throw a ball straight up from Earth what is the...
