CLASS 12 PHYSICS - ELECTROSTATICS ( Long and Short Questions Most probable)

ELECTROSTATICS (Long And Short Questions) Short Q: State Gauss's law in Electrostatics? State the properties of equipotential lines? What is electric dipole and dipole moment? Quantization of charge means? What is Coulomb's law? What is Electric field? Potential Difference? Electric flux? Equipotential Surface? Gauss Law? Capacitor? Capacitance? Use of capacitor? Long Q: Derive an expression for the Electric field intensity at a point on the equipotential line or, on broadside-on-position or, on TAN-B position of the Electric dipole? Derive an expression for Electric field intensity at a point on the axial line or, on end on position or,TAN-A position of the electric dipole? State Gauss's law of Electrostatics. Then give its application to derive for Electric field intensity due to uniformly Charged infinite planed sheet. Drive an expression for the Electric field intensity due to an infinitely long, straight wire of linear charge density \cm-. Drive Coulomb's law using...

What is Electrostatics?Class12

Electrostatics : Definition: It is branch of science which deals with the study of charges at rest. It is also known as static electricity or frictional electricity. Electric Charge: Electric charge is an Intrinsic property of the elementary particles like electrons, protons etc.of which all the objects are made up of. Quantization of charge: The quantization of charge means that charge can exist only as integral multiple of electronic charge i.e. q=+-ne,where n is an integer. • It was first suggested by by faraday. Charge conservation: In an isolated system,the total net charge of the system always remains constant. Charge is always associated with mass : Charge can not exist without mass though mass can be exist without charge. Additivity of charge:  Total charge of a system is the algebraic sum of all individual charges in the system. Charge is invariant:  Charge is independent of the frame of reference. Coulomb's Law:  Coulomb's law states that the magnitude of ...
