List of top Physics Questions on Gauss Law asked in KCET

A cubical Gaussian surface has side of length a = 10 cm. Electric field lines are parallel to x-axis as shown. The magnitudes of electric fields through surfaces ABCD and EFGH are 6kNC^-1 and 9kNC^-1 respectively. Then the total charge enclosed by the cube is
[Take ε₀ = 9 × 10^-12 Fm^-1]

The total electric flux through a closed spherical surface of radius ‘r’ enclosing an electric dipole of dipole moment 2aq is (Give ε₀ = permittivity of free space)
