Which change increases the electric force between objects?
-two neutral objects are moved closer together.
-electrons are added to two negatively charged objects.
-two oppositely charged objects are moved farther apart.
-the charge on two positively charged objects is reduced.

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
