Question
What is the net flux of the uniform electric field through a cube of side 20 cm oriented so that its faces are parallel to the coordinate planes?
Solution
The net electric flux through a closed surface in a uniform electric field is always zero. This is because the number of electric field lines entering the cube is equal to the number of lines leaving the cube. This is a direct consequence of Gauss's Law, which states that the net electric flux through a closed surface is equal to the charge enclosed by the surface divided by the permittivity of free space. In this case, there is no charge enclosed by the cube, so the net flux is zero.
