Warm-Up: Prerequisite Review

These questions review concepts needed for this section.

Coulomb's Law gives the force between two specific charges. What is the electric field concept designed to describe?

The same thing as Coulomb's force — they are identical.

The influence of a source charge on the space around it, independent of what test charge is placed there.

The force between two charges when one of them is very small.

The total force on all charges in a region.
