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 rest is the electrostatic force and is given by r F KQq r r E = 2 $ ( electrostatic force ) , where K = 8.99x10 9 Nm 2 /C 2 . The Force Between Two Moving Charged Particles: The force between two moving charged particles is the electromagnetic force and is given by r r r F r r cr vV r EM =+× × 22 2 $$ ( electromagnetic force ) where K = 8.99x10 9 Nm 2 /C 2 and c = 3x10 8 m/s speed of light in a vacuum ) . The first term is the electric force and the second ( new ) term is the called the
