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.

Force of interaction between two charged rods
double integration in a sense is like doing two normal integrations. Find the electric field due to the whole rod on an arbitrary point then integrate to find the total force.

Calculating electric field in a dielectric
Why the electric field calculated in a dielectric is equal to the uniform charge density per unit area divided by epsilon-0 (which is the permitivity in space) shouldn't it be divided by another const …

Why as distance decreases capacitance increases?
I understand mathematically that as the distance between the capacitor plates decreases, capacitance increases, but I find there is a small contradiction that I want to understand. If the capacitance …
