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 […]
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
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
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.
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
