A negatively charged metal rod being brought close to a positively charged foil balloon. The two objects are 0.2 meters apart and the foil balloon has a charge of -5.0 x 10^-12, the metal rod has a charge of 3.2 x 10^-12. (10 to the power of -12)

1. Draw a free body diagram of the system under investigation, with vectors to show the strength of the forces we're observing.

2. Explain how your diagram shows the forces acting on the objects in the system. DRAWING

3. Draw a model to show how the distribution of charge will change if we bring this positively charged balloon close to a negatively charged balloon.

4. Given the charge of each of these objects, what is the strength of the force that draws them together?

A.  -2.0 x 10-12

B.  -4.0 x 10-10

C.  2.3 x 10-12

D.  4.0 x 10-10

5. Explain how your model shows how the distribution of charge will change if we bring this positively charged balloon close to a negatively charged balloon.

6. This interaction shows a __________ force, because a __________ force would push the objects away from each other.

A.  negative

B.  positive

7. Use Coulomb's Law to explain how the force between these objects would change if they were 0.4 meters apart, instead of 0.2 meters apart.
