# NCERT

Q 1.17 (b): 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\times 10^{3}\frac{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?

H Harsh Kankaria

Using Gauss's law , we know that  \phi = q/\epsilon _{0}

Since flux is zero, q = 0, but this q is the net charge enclosed by the surface.

Hence, we can conclusively say that net charge is zero, but we cannot conclude that there are no charges inside the box.
