Consider the following statements regarding Gauss Law:1.Gauss law states that the total electric flux through a closed surface is equal to charge enclosed divided by permittivity.2.It is particularly useful for calculating electric fields with high symmetry such as spherical or cylindrical distributions.3.Gauss law can be used to determine field due to any arbitrary charge distribution easily.4.Electric flux depends on the enclosed charge and not on the shape of Gaussian surface.Which of the above statements is/are correct?
