Question

The electric flux through the surface

Answer 1

To get the solution for this question, we need to first understand which theorem can be applied to get the net electric flux through the surface. Once the theorem is identified, then according to the theorem, it will be easy for us to get the net charge from the surface which will help us to get the electric flux through the surface.

Complete solution:
We know that, to get the electric flux through the surface we can use the Gauss Theorem of electrostatic to get the answer.
Gauss's law for the electric field which describes the static electric field generated by a distribution of electric charges. It states that the electric flux through any closed surface is directly proportional to the total electric charge enclosed by this surface.
As per Gauss's theorem in electrostatics, the electric flux through any closed surface depends only on the amount of charge enclosed by the closed surface. It does not depend on the size and shape of the closed surface.

Therefore, the electric flux through all the closed surfaces is the same for all the given figures.

Note:
To get the solution for this question, one should know the laws of electric field, which will help to get the electric field of any surface that is mentioned in the question. There are different laws in electrostatics, but Gauss law is the most effective law and it helps to solve many electrostatic problems easily, if you have the proper understanding of this law.
