Electric Field

Electric Field Strength,E :pencil2: At any point is define as the force per unit charge, exerted on a test charge,q1 placed at that point a distance,r from a point charge,q
-
-
Conductor :pencil2: Materials are permit electrons from each atom to move freely through the materials.
Insulators :pencil2: All the electrons are bound to the individual atoms.It can be transferred to @ from the surfaces of insulators by rubbing @ heat through friction.
-
Charge Exert Force :pencil2: In an atom, the force that holds an electron near the nucleus(consist protons) is the electrical force. :pencil2: Assumed to be at rest @ moving very slowly. Electric force under these condition called electrostatic forces.
Gauss' Law
the net electric flux through any closed surface is directly proportional to the enclosed net electric charge.

-
Coulomb's Law
-
-
The magnitude of electric force that a charged particle exerts on another charged particle is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.The direction of the force is along the line joining them.
Electric Charges
-
-
-
Law of Conservation of Charge
:pencil2: states that the net charge of a closed system never changes.
Quantization of Charge 
:pencil2: the physical property of matter that causes it to experience a force when placed in an electromagnetic field.
