Gauss' Law and a Gaussian Sphere

[victorializ]

Homework Statement

A Gaussian Sphere with a radius of 1m surrounds an unknown charge at the center. At this surface a uniform outward directed electric field is 1 N/C. Use Gauss' Law to calculate the amount of charge enclosed by the sphere.

Homework Equations

E = q/4∏εor^2

The Attempt at a Solution

i've been reading about gauss' law in my physics book and i thought that the charge inside a gaussian sphere was always zero? or is that only for an electric field?

The Electric Field (under static conditions) is zero within the conducting material of a conductor. A Gaussian surface is simply any closed surface over which it is convenient to apply Gauss's Law.
