Question

If we want to apply Gauss's Law on an infinite length line of charges, how much open surfaces we can obtain in the closed cylindrical Gaussian surface?

Answer 1

2

Step-by-step explanation:

There are two open surfaces obtained in a closed cylindrical Gaussian surface when we apply Gauss's Law on an infinite length line of charges. The two surfaces are the upper circular base and the lower circular base.

Moreover, Gauss Law states that the net electric flow outside to a closed surface is proportional to the electric charge within the closed surface.
