Question

Do electric flux passing through a 3d object is always 0?

Answer 1

Electric Flux:

1. If and only if there is no net charge in the volume enclosed by the surface, the flux of an electric field through a closed surface is always zero.
2. The amount of electric flux is always proportional to the surface charges. So, regardless of the outside charge, the net charge for a 3D object is always zero.
3. The electric flux through a closed surface is proportional to the net charge enclosed by the surface, according to Gauss' law. Thus, when the net charge enclosed by the surface is zero, the electric flux through the closed surface is zero.
4. The electric field lines in an electric dipole begin at the positive charge and end at the negative charge. As a result, the electric field lines originating from the positive charge will contribute a positive flux at the cube's surface.
5. The same field lines, however, will have to cross the side again to reach the negative pole. As a result, it will contribute the same amount of negative electrical flux.
6. As a result, positive and electric flux cancel each other out, yielding a net electric flux of zero.
