1.3 The superposition of Coulomb's forces

In the following visual we see the effect, superposition, of two charged particles on a third one. The conclusions can be generalized to any number of particles.

Electric force
What we already know
Coulomb's law
More than two charged particles
Conclusions
The concept of field intensity
Field intensity
Lines of force
Conclusions
Potential energy and potential
What are these magnitudes?
Superposition. Work in the field
Conclusions
Potential, field and movement of charged particles
Relation between field intensity and potential
Movement of charged particles
Conclusions
