Electric Field on Perpendicular Bisector of Straight Charged Wire | video in HINDI | EduPoint

In this Physics video lecture in Hindi we evaluated the electric field intensity at a point on the perpendicular bisector of a straight charged wire of linear charge density λ. Other relevent topics : Electric Charge : The property of a proton or an electron, which gives rise to electrostatic force between them, is called electric charge . It is a scalar quantity. In S.I., its unit is coulomb (C). A proton possesses +e charge, whereas, an electron possesses –e charge, where, e =1.6 × 10 ^(-19) C. Additive nature of charge : - The total charge on an object is equal to the algebraic sum of all the electric charges distributed in that object. If q1, q2, ……….. qn are the charges distributed in an object, then the total charge on that object, q = q1+ q2+ …….+ qn Quantization of charge : - The fact that all observable charges are always some integral multiple of elementary charge e, is known as quantization of charge. Hence, any observable charge, q = ± n e Law of conservation of charge :- Law of conservation of charge states that for an isolated system, the net charge always remains constant. In other words, charge can neither be created nor be destroyed. Coulomb's Law : Coulomb's law in electrostatics states that the magnitude of the electrostatic force between two charges is directly proportional to the product of the magnitudes of two charges and inversely proportional to the square of the distance between them. Coulomb's constant is having value 9 × 10 ^9 Nm^2 C^(-2). Absolute permittivity of free space and is equal to 8.854 ×10^(-12) C^2 N^(-1) m^(-2). The principle of superposition : - This principle states that when a number of charges are interacting, the electrostatic force between two charges is not affected by the existence of the other charges and the total electrostatic force on a charge is the vector sum of all the forces due to other charges. ★★★★★★★★★★★★★★★★★★★★★★★★ Click to visit the homepage of our channel :    / @edupoint.physics   EduPoint, Dam Road, Chandil, Dist- Seraikela-Kharsawan, Jharkhand, India.
