A ring of charge is defined as follows:
The ring has units of charge per unit length. Let be the electric flux through the half of a sphere of radius centered on the origin, and let be the electric flux through the half.
Determine the following ratio:
Details and Assumptions:
1)
Electric permittivity
2)
Use outward-facing surface normal vectors
Note: I probably should have rated this "Hard", but I clicked "Medium" instead
