Fill in the word that completes each statement. Building up electric charges on a Van de Graaff generator is an example of static . Lightning is an example of static .
As the distance between two charged objects increases, the strength of the electrical force between the objects
As the amount of charge on two objects increases, the strength of the electrical force between the objects
Sonia was experimenting with electric charges. She tied two inflated balloons together, held them next to each other, and rubbed both with a piece of wool.What did Sonia observe, and why?
Sonia observed that the two balloons repelled each other and moved apart. This is because both balloons acquired the same electrical charge when they were rubbed with the wool, and like charges repel each other.
Describe what happens to the electric field lines when two objects with unlike charges are brought near each other.
When two objects with unlike charges are brought near each other, their electric field lines combine and bend toward each other. The field lines start on the positive charge and end on the negative charge, indicating that the two objects are attracted to one another.
