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.

WebMay 5, 2024 · The bigger dark gray sphere has uniform positive charge density rho, and so its E-field is nice and points radially outward. Now the smaller sphere has uniform charge density rho too, but negative now. Such that by putting it in, we effectively create a hollow sphere with no enclosed charge. WebMar 10, 2024 · And, of course, in general the sphere could have an asymmetrical cavity. Only the outer surface needs to be spherical. Let me try one last time to be understood. a) You might claim that an E-field of zero could be created inside the conductor by a combination of the point charge and a (non-uniform) distribution on the inner surface.
