Overall Electric flux of a rigid body

[Lushikato]

When we looked at some closed surface, we defined the overall electric flux of that surface as the sum of all infinitesimal fluxes of all the infinitesimal surfaces that make the quoted closed surface. Does that change if we do not have a closed surface, but a rigid body such as, let's say, a stone? What would the electric flux of that stone be?

Hello Lushikato,

Same thing. What goes in minus what goes out. And going in and out can only be through the surface ...

All right, thank you!
