The ultimate result of the divergence theorem evaluates which one of the following?(a) Field intensity(b) Field density(c) Potential(d) Charge and fluxI got this question in exam.I need to ask this question from Surface Integral in section Vector Calculus of Electromagnetic Theory

Answer»

The CORRECT choice is (d) CHARGE and flux

Explanation: Gauss law STATES that the ELECTRIC flux passing through any closed SURFACE is equal to the total charge enclosed by the surface. Thus, it is given by, ψ = ∫∫ D.ds= Q, where the divergence theorem computes the charge and flux, which are both the same.
