This simulation visualizes the electric field and electric potential along the x-axis for two charged particles.

How to Use:

• Click-and-drag the particles to move them left or right.
• The particle on the left is confined to the region left of the origin.
• The particle on the right is confined to the region right of the origin.
• Use the sliders in the Controls panel to adjust the charges of the particles.

Graph Interpretation:

On the graph:

• The electric field (purple) is shown as positive if directed to the right, negative if directed left.
• The electric potential (green) shows the potential energy per unit charge.
• You can choose to display only the field, only the potential, or both using the buttons in the Controls panel.

Red particles represent positive charges, blue particles represent negative charges.
