Absolute Permittivity of Medium
Chapter-1|Electric Charges and Fields | NCERT 12th Physics: Absolute Permittivity of Medium: (Dielectric Constant):- The force between two charges q₁ and q₂ located at a distance r apart in a medium may be written as-
Comparison of Coulomb’s law with Gravitational law
Chapter-1|Electric Charges and Fields | NCERT 12th Physics: Comparison of Coulomb’s law with Gravitational law: Both the Coulomb’s and Newton’s Law follow Inverse Square Law. Electric force can be attractive or repulsive, But gravitational force is always attractive in nature.

Coulomb’s Law in Vector Form
Chapter-1|Electric Charges and Fields | NCERT 12th Physics: Coulomb’s Law in Vector Form: We consider two positive charges q₁ and q₂ are placed in vacuum at a distance r from each other. They repel to each other. According to Coulomb’s law the magnitude of force on charge q₁ due to q₂ is given by
Coulomb’s Law
Chapter-1|Electric Charges and Fields | NCERT 12th Physics: Coulomb’s Law: Coulomb’s law states that the force of attraction or repulsion between two stationary point charges is (I) Directly proportional to the product of the magnitudes of the two charges and (II) Inversely proportional to the square of the distances between them. This force acts along
Basic Properties of Electric Charge
Chapter-1|Electric Charges and Fields | NCERT 12th Physics: Basic properties of electric charge:- From the experimental observation the electric charge has following three basic properties. 1.Additive nature of electric charge:- Electric charge is additive in nature, that means the total charge of the system is the algebraic sum of all the individual charges located at different
Charging by Induction
Chapter-1|Electric Charges and Fields | NCERT 12th Physics: Charging by Induction:- The process of charging a neutral body by bringing a charged body nearby it without making contact between the two bodies is known as charging by induction. Using the process of charging by induction, conductor may be charged permanently. Process:- 1. For charging
Conductors and Insulators
Chapter-1|Electric Charges and Fields | NCERT 12th Physics: Conductors: The substance through which electric charges can flow easily are called conductors. They contain a large number of free electrons which make them good conductor of electricity. Examples: Metals, Human, Animals bodies e.t.c. Insulators: The substance through which electric charges cannot flow easily are called insulators.
Electrostatics and Electric Charge
Chapter-1|Electric Charges and Fields | NCERT 12th Physics: Electrostatics: Electrostatics is the study of electric charges at rest. Here we study the forces, fields, and potentials associated with the static charges. Electric Charges: Electric charge in an intrinsic property of elementary particles of matter which gives rise to the electric force between various objects. Electric
Hysteresis Curve
Hysteresis Curve: NCERT Class 12th Physics || Chapter-5 || Magnetism and Matter: The hysteresis Curve represent the relation between the magnetic induction B or intensity of magnetisation I of a ferromagnetic material with magnetic intensity H. The graph shows the behaviour of the material as we take it through one cycle of magnetisation. Formation of
