Gauss' flux theorem
Web1 Gauss’ integral theorem for tensors You know from your undergrad studies that if ~uis a vector eld in a volume ˆR3, then Z div~udV = S ~udS~ (1) where Sis the surface of (in mathematical notation, S= @). dS~ is a unit vector, perpendicular to a local surface. This is called Gauss’ theorem, and it also works for tensors: Z divAdV = @ AdS~ (2) Webelectric field: A region of space around a charged particle, or between two voltages; it exerts a force on charged objects in its vicinity. Gauss's law, also known as Gauss's flux theorem, is a law relating the distribution of electric charge to the resulting electric field. The law was formulated by Carl Friedrich Gauss (see ) in 1835, but was ...

WebMay 17, 2024 · If the electric field at P1 is E1, the flux of it will be E1A. Similarly the flux through P2 will be -E2A (assuming the direction of area vector). The area of the surfaces being the same, the field clearly is different at P1 and P2, because the two planes are seperated by a distance = a. Thus if E1 = K/ (x^2) then E2 must be K/ (x±a)^2.
In physics and electromagnetism, Gauss's law, also known as Gauss's flux theorem, (or sometimes simply called Gauss's theorem) is a law relating the distribution of electric charge to the resulting electric field.
