Careful measurement of the electric field at the surface of a black box indicates that the net outward flux through the surface of the box is `8.0 xx 10^3 Nm^2//C`. If the net outward flux through the surface of the box were zero, could you conclude that there were no charges inside the box? Why or Why not?
