- The total electric field at a point is equal to the vector sum of the fields due to each source charge.
- The total electric force experienced by a single charge at a point is equal to the vector sum of the forces due to each source charge.

This is the superposition principle.

**Click** on “Field at any point” and click into the screen to show the field at any point.

**Click **on the button "drag the charge" then drag the test charge to compute the force at any point of the plane.

- To illustrate an application of the principle of superposition to find the field created by two single charges
