Net Charge of a Region with Increasing Electric Field?

[affordable]

Homework Statement

If in a region, the electric field, points to the right and the electric field increases as it moves right, what net charge does the region have?

Homework Equations

The Attempt at a Solution

I assume that the region has a net positive charge as the magnitude increases with increasing charge under Gauss's Law, but can the region have a net negative charge or would a net negative charge have the magnitude increase in the opposite direction?

hi affordable!

hint: what is the flux through a box?

(and what would be the flux be if (instead) it was decreasing to the right?)

Oh thank you lol. I forgot to use that net flux = q enclosed over epsilon.
