Vedclass · Answer

(D) The Maxwell's equations in integral form are as follows:$A$. Gauss's law of magnetostatics states that the net magnetic flux through any closed surface is zero: $\oint \vec{B} \cdot d\vec{a} = 0$ $(A-II)$.$B$. Faraday's law of electromagnetic induction states that the induced electromotive force in a closed loop is equal to the negative rate of change of magnetic flux through the loop: $\oint \vec{E} \cdot d\vec{l} = -\frac{d}{dt} \int \vec{B} \cdot d\vec{a}$ $(B-III)$.$C$. Ampere's law (in its original form) relates the line integral of the magnetic field around a closed loop to the current passing through the surface enclosed by the loop: $\oint \vec{B} \cdot d\vec{l} = \mu_0 I$ $(C-IV)$.$D$. Gauss's law of electrostatics states that the total electric flux through a closed surface is equal to the total charge enclosed divided by the permittivity of free space: $\oint \vec{E} \cdot d\vec{a} = \frac{1}{\epsilon_0} \int \rho dV$ $(D-I)$.Thus,the correct matching is $A-II, B-III, C-IV, D-I$.
