Two equations are given below: A. \(\oint \mathbf{E} \cdot d \mathbf{A}=\frac{Q}{\varepsilon_0}\) B. \(\oint \mathbf{B} \cdot d \mathbf{A}=0\) 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
- D Both A and B represents Faraday's law
Answer & Solution
Correct Answer
(B) A. Gauss law for electric fields B. Gauss law for magnetic fields
Step-by-step Solution
Detailed explanation
(A) \(\oint \mathrm{E} \cdot d \mathrm{~A}=\frac{Q}{E_0}\) It is Gauss law of electrostatic fields. (B) \(\oint \mathrm{B} \cdot d \mathrm{~A}=0\) Because single pole of a magnet does not exist. So, it is Gauss law for magnetic fields. Option (b) is correct.
