is considered as positive flux , then the field lines going into the surface will be considered as negative flux. So, in this case the net flux is , φ = — q /ε₀ If two opposite point charges but same magnitude are put inside a closed surface, then Σ q = +q — q = 0 So, φ = 0/ε₀ or, φ = 0 As, you can
