6. Summarize: Fill in the blanks. The electrostatic force between two objects is directly
proportional to the
of the charges, and
the distance
7. Summarize: As the magnitude of the charges increases, the force between them
As the distance between the charges increases, the force between
them
proportional to
8. Challenge: Coulomb's law is an equation that relates the electrostatic force between two
objects to their distance and charge. In activity A, you found that the electrostatic force
between two objects is proportional to the product of their charges. Combine that with what
you have learned in this activity to complete Coulomb's law below. (Hint: In the equation, k
is a constant.) Check your answer with your teacher.
