What are some real-world applications of Gauss' Law?

[Clol]

Homework Statement

I'm almost done writing a paper on Gauss' Law and for my final body paragraph I want to include some interesting applications of Gauss' Law. I mean applications as in what has Gauss' Law helped to create or invent- something relatively tangible.

The Attempt at a Solution

I understand the connection with Faraday's Cage rather well. I know that it has magnetism and gravity analogues. Other than that I have been unable to find anything. I'd imagine since there are so many comparisons of electric flux with air flow, there might be some application out there having to do with falling objects or objects floating in water but I can't find anything to reinforce these suppositions enough to put them in my paper.

You may use gravity field flux and according to the gauss law inside the spherical shell there is no gravity field.You may prove it by taking some easy integrals

There's a huge application of gauss law in engineering field. We have to do a lot of analysis with this law.
