# Gauss' Law - electric field

Gustavo

## Homework Statement

An infinite metal plate has a surface density of charge σL=-6μC/m² , Left side and a surface density Of load σR=+4μC/m² , in the right side. A Gaussian surface In the form of a circular cylinder, with area A 12 cm², is Located with the left side inside the plaque and a thin Plate loaded to the right. The surface charge density of the Metal plate is σA. Check the correct option with respect to the density value Superficial σA And flow ΦE Through the Gaussian.

## Homework Equations

Gauss law for an infinite plate: E=|σ|/2ε0

## The Attempt at a Solution

I could not understand the problem, I do not know how to find the density and nor the flow. I tried to use Gauss's Law but I could not understand the problem.
