PPT-Ch 18: Electric Force & Electric Fields

The Origin of Electricity The electrical nature of matter comes from atomic structure Nucleus made up of protons and neutrons Most of the mass of the atom is contained in the nucleus. Britain has the most developed system with the oldest Imperial award for naval long service introduced by King William IV in 1831 The Defence Force Service Awards were established on 20 April 198 2 by Letters Patent providing distinctive Australian In addition magnetic fields create a force only on moving charges The direction the magnetic field produced by a moving charge is perpendicular to the direction of motion The direction of the force due to a magnetic field is perpendicular to the dir Physics 2415 Lecture 3.

What is electric force?. Coulomb’s law. The symbol . k. is a proportionality constant known as the Coulomb's law constant. The value of this constant is dependent upon the medium that the charged objects are immersed in. In the case of air, the value is approximately 9.0 x 10^9 N • m^2 / C^2. . 3.1 .
