4. If the same two dust particles have -1.0 x 10-10 C of charge on one, and
+3.2 C x 10-10 C on the other, what is the force between them now? If the force is pushing them apart, show it as a positive number and if it is attracting them together, show it as a negative number. Explain your response.
