3. I have two identical dust particles. They are spheres with diameters of 0.0001 meter (about the same as a hair). They have the same density as water so they each have a mass of 1012 kg. If each dust particle goes through a discharge so that 2.40 „e 1010 C of electrons stick on each of them, what is the force between the two dust particles when they are 0.001 meters apart? 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.

Isn't this Coulomb's Law? You have q1;q2, d .
