electrostatics - Field between the plates of a parallel plate …
If we try getting the resultant field using Gauss's Law, enclosing the plate in a Gaussian surface as shown, there is flux only through the face parallel to the positive plate and outside it (since …
electrostatics - Why is the net electric field due to an external ...
2024年12月1日 · The electric field due to an external charge of a Gaussian surface is not zero inside its volume. The total electric flux is zero, since it only depends on the charges inside the …
What is the "practical purpose" of Gaussian surfaces?
2015年10月14日 · First of all, the usage of Gaussian surfaces is based on Gauss's law, which is mathematically equivalent to Coulomb's law. So you are right in saying that fundamentally, …
Why does Gauss' Law appear to neglect charge outside the …
2021年3月5日 · Why does the charge inside the Gaussian surface only contribute to the electric field? I would think that the charge outside the Gaussian surface also causes an electric field …
electrostatics - How is adding a charge outside a Gaussian surface ...
2021年8月6日 · If you then add a charge outside of the constructed Gaussian surface, the Q enclosed remains the same. Therefore the calculation and the E calculated would be the same …
Why are all the Gaussian surfaces very long or infinite?
2024年4月23日 · The immediate counter-example is a spherical surface around a point charge or a charged sphere. As the others have already pointed out, the choice of the surface has to do …
electrostatics - How to choose the best Gaussian surface? Are …
2018年4月20日 · Choose the Gaussian surface in such that the electric field at every point on it is constant. Ultimately, you should be looking for symmetries, since it would simplify calculations …
Gaussian surface and Gauss law - Physics Stack Exchange
2024年2月29日 · Since, Gaussian surface is a closed surface which has a constant electric field but in this case the both the magnitude and direction of electric field is changing at different …
Gaussian surface and closed surfaces - Physics Stack Exchange
2018年8月24日 · So the requirement for a surface to be closed is that it (1) is compact and (2) has no boundary. Compactness is a topological property: a surface or other topological set is said …
How to choose Gaussian surfaces while solving problems?
$\begingroup$ You chose the Gaussian surface to simplify you own life. That usually means taking advantage of some symmetries in the problem to allow you to say that "the flux thought …
