Question

flux through closed surface maybe
​

Answer 1

all existing matter and space considered as a whole; the cosmos. The universe is believed to be at least 10 billion light years in diameter and contains a vast number of galaxies; it has been expanding since its creation in the Big Bang about 13 billion years ago.

Answer 2

Explanation:

Gauss's law says that the net flux through a closed surface is equal to q/ϵ0 where q is the charge enclosed in the surface. ... For a uniform electric field, any closed surface will have equal number of field lines entering the surface as exiting the surface and so the total flux across that surface will be 0 as required .
