Mark the correct options: Gauss's law is valid only for uniform charge distributions. Gauss's law is valid only for charges placed in vacuum. The electric field calculated by Gauss's law is the field due to all the charges. The flux of the electric field through a closed surface due to all the charges is equal to the flux due to the charges enclosed by the surface.

Statement -1 : Electric field of a dipole can't be found using only Gauss law. (i. e. without using superposition principle) Statement - 2 : Gauss law is valid only for symmetrical charge distribution

If electric field around a surface is given by |vec(E)|=(Q_(in))/(epsilon_0|A|) where 'A' is the normal area of surface and Q_(in) is the charge enclosed by the surface. This relation of gauss's law is valid when
