To find the electrostatic potential of a charged disk with radius R and surface charge density σ, the problem becomes complex when calculating points other than the center. The discussion highlights that while the potential can be determined at the origin and the rim of the disk, finding it at arbitrary points remains challenging. Bessel functions are referenced as a mathematical tool used in solving this problem, although some participants express uncertainty about their application. The complexity of the calculations suggests a deeper understanding of advanced mathematical concepts may be necessary. Overall, the electrostatic potential of a charged disk is a nuanced topic requiring specialized knowledge.
I have a common plasma globe with blue streamers and orange pads at both ends. The orange light is emitted by neon and the blue light is presumably emitted by argon and xenon.
Why are the streamers blue while the pads at both ends are orange? A plasma globe's electric field is strong near the central electrode, decreasing with distance, so I would not expect the orange color at both ends.
