Electric Charge, Coulomb's Law, Electric field, electric dipole Examples
Description
Electrostatics is a branch of physics that studies electric charges at rest. The phenomena arise from the forces, known as electrostatic force, that electric charges exert on each other. Such forces are described by Coulomb's law.
So studying electrostatics, first of all concepts of electric charge, is introduced. It's important to know the properties of electric charge; what is meant by conservation of charge and quantization of charge? Coulombs Law describe the relationship between electrostatics force and the magnitudes of charges and the distance between the charges in question.
In this course we discuss that how to find the electric force on a particle A of charge =q1 when the particle is placed near a particle B of charge =q2. A question of interest is :
How does particle A know of the presence of particle 2?
Since the particles do not touch, how can a particle can push or pull other particle? —how can there be such an action at a distance?
That charged particles set up an electric field in the space surrounding themselves can answer these questions. If we place a charged particle at any given point in that space, the particle knows of the presence of particle that because it is affected by the electric field that particle has already set up at that point.Thus, a charged particle pushes on other particle not by touching it but by means of the electric field produced by that charged particle.
Our goal in this course is to define an electric field and discuss how to calculate it for various arrangements of charged particles using different examples and problems.
