PURPOSE: To aid in visualization of equipotentials and lines of force.
DESCRIPTION: This model represents the equipotentials and lines of force for two nearby positive charges; it is quantitatively correct for charges of +Q and +3Q respectively. The height of the surface represents the potential; the black lines are equipotential surfaces. The blue lines represent lines of force.
REFERENCES: (PIRA unknown.)
EQUIPMENT: Equipotential model.
SETUP TIME: None.
