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 [tag:electromagnetism] and/or [tag:magnetic-fields]

We do take into account the field due to both plates in the cylindrical geometry. The field due to an infinite uniformly charged cylinder is zero in the interior of the cylinder, as can be shown by sy …

If you are beginning with electrostatics, you must have been introduced to Coulomb's Law for force between two point charges $q_1$ and $q_2$: $$ F \propto \frac{q_1 q_2}{r^2} $$ where $r$ is the …

Short answer: measurements would not change if the earth is taken to be at $100V$ instead of $0V$. The physically measurable quantity in electrostatics is the electric field, derived from the …
