Introduction

Summary

Principle of superposition: The total electric field at a point is the vector sum of the fields at this point due to each point charge.

Click on the point charge to change its sign. Click on the screen to make the lines of force visible.

Goals

• To show the vector addition at any point in a plane containing two point charges.
• To make visible the field lines of the four possible configurations.
