Physics/Gaussian surface


Tensae Lemma wrote at 2012-12-30 07:07:45
Gauss's law provide* an easy means of finding E or D for symmetrical charge distributions

such as a point charge, an infinite line charge, an infinite cylindrical surface

charge, and a spherical distribution of charge. A continuous charge distribution has rectangular

symmetry if it depends only on x (or y or z), cylindrical symmetry if it depends only

on p, or spherical symmetry if it depends only on r (independent of 6 and <j>). It must be

stressed that whether the charge distribution is symmetric or not, Gauss's law always

I would be delighted to help with questions up through the first year of college Physics. Particularly Electricity, Electronics and Newtonian Mechanics (motion, acceleration etc.). I decline questions on relativity and Atomic Physics. I also could discuss the Space Shuttle and space flight in general.


I have a BS in Physics and an MS in Electrical Engineering. I am retired now. My professional career was in Electrical Engineering with considerable time spent working with accelerometers, gyroscopes and flight dynamics (Physics related topics) while working on the Space Shuttle. I gave formal classroom lessons to technical co-workers periodically over a several year period.
