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.

|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|
|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|
