Questions tagged [electrostatics]
Electrostatics is concerned with the electrical fields and scalar potentials of stationary electrical charges and charge distributions. Use this for questions about electromagnetic situations in which currents and magnetic fields are absent, otherwise use the [electromagnetism] and/or [magnetic-fields] tags.

Does the electric potential energy of a positively-charged particle vary directly with its distance from a charged particle or surface?
Current high school AP Physics II student here, so apologies if this question comes off as unlearned.
I'm trying to learn about electric potential in my class, but I realize I still don't understand ...

How is the $E$ field at the surface of a charged rod affected by its dielectric constant?
I am seeking clarification on a concept from a test question I have been studying.
Essentially, the question gives an example of an infinitely long charged rod, made of an insulating material. The rod ...
