PHY2061 R. D. Field Department of Physics chp32_1.doc University of Florida The Electromagnetic Force The Force Between Two-Charged Particles (at rest): The force between two charged particles at restis the electrostatic forceand is given by rFKQqrrE=2$(electrostatic force) , where K = 8.99x109Nm2/C2. The Force Between Two Moving Charged Particles: The force between two movingcharged particles is the electromagnetic forceand is given by rrrFrrcrvVrEM=+××222$$(electromagnetic force) where K = 8.99x109Nm2/C2and c = 3x108m/sspeed of light in a vacuum). The first term is the electric forceand the second (new) term is the called the
