Two equations are given below:
$A. \oint E \cdot dA = \frac{Q}{\varepsilon_0}$
$B. \oint B \cdot dA = 0$
They are:
$A. \oint E \cdot dA = \frac{Q}{\varepsilon_0}$
$B. \oint B \cdot dA = 0$
They are:
- A$A$. Ampere's law, $B$. Gauss law for electricity
- B$A$. Gauss law for electric fields, $B$. Gauss law for magnetic fields
- C$A$. Faraday's law, $B$. Gauss law for electric fields
- DBoth $A$ and $B$ represent Faraday's law
