Part E: Conclusions about the Electric Field

Questions

Please answer the questions below.

Click on Setup in the model above. The gray lines in the space are manmade constructs called electric field lines. What is the only factor that changes the number of lines, and therefore the angular spacing between lines, in the area where the field is located?

How can you determine the relative strength of the electric field compared to other locations by examining just the lines and their relationship to each other?

How does changing the point charge, q, value in the field affect the electric field, E, created by the source charge?

How does changing the point charge, q, in the field from positive to negative affect the magnitude and direction of the force vector on that charge, q?
