About the case of "surface charge density". The electric field perpendicular to the surface is E=σ/(2*ε). The Gauss surface must pass through the plate.
And black hole mechanics it's a giant magnet -43 me iron in space a little different but to speed you can with space to half par can to speed curvature get first born universe math to the hole rim equator or faster to the magnet gauss lines ring galaxy to its curvature to a spaced N42 magnet around 1.2cm to 2cm gap spin it very slow you should see the iron as you turn it bind to the hole rim at centre it should ball as you see two arms via the centre line to the direction of spin to base you in iron should see the mechanism for spiral arms galaxy primarily the first. Have fun once done and increase the speed difference between material is the only difference between examples this is rough guide.

clear and simple as always))) keep going please))
