The quantitative relationship for the force between two point charges is Coulomb’s Law: = force (N), = charge in coulombs (C), F Q = distance between point charges (m). r k = 9.00 x 109 Nm2/C2 Example 3: Find the electrostatic force between two stationary electrons 8.0 µm apart. What is the instantaneous acceleration if one of the electrons is released? What if the distance is increased to 40 µm? 2 Combining Forces between Multiple Particles — Example 1: Three protons are placed on a line at 0 m, 0.40 m, 0.90 m. Find the force on each proton.
