Coulomb's Law Worksheet. Coulomb force is true only for static charges. If two charged particles have charges q 1 and q 2 and are a distance r apart, the particles exert forces on each other of magnitude… 𝐹 1 1 2= 𝐹 2 1= 𝐾 2 2 where k and is the electrostatic constant (8.99×109 nm2/c2).
Find the electrostatic force between charges of +2.0 c and +5.0 c separated by a distance of 75 m in a vacuum. What is the force between the two charges? What is the force between the particles?
