Question

what is the importance of gauss's theorem in electrostatic?​

Answer 1

This equation is called Gauss' law. Thus Gauss' law states that electric flux through any closed surface is equal to the net charge enclosed inside the surface divided by permittivity of vacuum. The reader can find more rigorous proof of Gauss' law in any high level Physics book.

Answer 2

Answer:

Gauss's theorem is of great importance. Those situations, in which the calculation of electric field by applying Coulomb's law or the principle of superposition of electric field becomes very difficult, the results can be obtained by applying Gauss's theorem with great ease.

Explanation:

Gauss' theorem states that the total electric flux through a closed surface enclosing a charge is equal to 1/ε₀ times the magnitude of the charge enclosed.
