Electrostatics Notes 
In this video we will give you best Notes of  chapter #Electrostatics  for preparation of NEET ,JEE, AIIMS and Other competitive Exams and also for Boards .
Note –  Electrostatics is a branch of physics that studies electric charges at rest.
            Electrostatic phenomena arise from the forces that electric charges exert on each other. 
            Such forces are described by Coulomb’s law.

Vocabulary
electrostatics the study of interaction between electric charges which are not moving
electric charge a fundamental property of matter, either positive or negative
electrons negatively charged particles in matter
protons positively charged particles in matter
law of conservation of electric charge the net amount of electric charge produced in any process is zero (electric charge cannot be created or destroyed)
electrostatic force opposite charges attract, like charges repel.
coulomb the SI unit of charge
insulator a material in which the electrons are tightly held by the nuclei and are not free to move through the material (examples: glass, rubber, plastic, dry wood)
conductor materials through which electrons are free to move (examples: metals, silver, copper, gold, mercury)
semiconductor conduct at high temperatures only (examples: silicon, germanium, carbon)
charging by contact electric charge is transferred from a charged object to an uncharged object
charging by induction an electrically charged object is brought near but does not touch an uncharged object causing a separation of charges. When grounded, may provide a permanent charge
Coulomb’s Law The magnitude of the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between the charges.
electric field region where electric force may be felt surrounding a charged object. Represented by lines that start on a + charge and end on a – charge.
electric flux the amount of field passing through a certain area
Gauss’s Law the total flux through a surface is proportional to the magnitude of the electric field and the cross sectional area of the surface
quantized to limit the possible values to a discrete multiple of a minimum value
invariant unchanged
electroscope used to detect the presence of a charge on an object by the movement of thin metallic leaves due to charge increase or decrease
