WebKhan actually mentions that at the end of the next video in this series: that for a finite plate where you are far away from the edge, this theory holds, so yes, you are correct. However, just remember that right near the edge, things fall apart. Most theories are really good approximations; the only real values come when you test experimentally.

WebSep 6, 2012 · Since the sphere is not a shell, the E is not 0. And it should be found by considering a concentric Gaussian sphere with radius smaller than R.
