Electric Field Lines

Again uncheck the box labeled, “Electric Field.” Check the box that says “Grid.” Place a +1nC and a –1nC charge on the screen 20 grid marks apart. (Such a configuration of charges is called a dipole). Use the yellow E-field Sensors to probe the electric field around the two charges.

Questions

Please answer the questions below.

In what place or places is the field the strongest?

In what place or places is the field the weakest?

Check the box titled, “Electric Field.” What appears? What do these arrows represent?

In general, we draw electric field lines as shown below, by connecting what would be a set of arrows into a smooth curve.

When examining this type of field drawing, how is the field strength conveyed? What about the field direction? Explain.
