Question

The Maxwell's four equations are written as
(i) $\oint\limits_{s} \vec{E} \cdot \vec{d} s=\frac{q}{\varepsilon_{0}}$
(ii) $\oint\limits_{s} \vec{B} \cdot \vec{d} s=0$
(iii) $\oint\limits_{s} \vec{E} \cdot \vec{d} l=\frac{d}{d t} \int\limits_{s} B \cdot d s$
(iv) $\oint\limits_{s} \vec{B} \cdot \vec{d} l=\mu_{0} I+\varepsilon_{0} \frac{d}{d t} \int \vec{E} \cdot \vec{d} s$

• A. (i), (ii), (iv)
• B. (i) and (iii) only
• C. (i), (ii), (iii)
• D. (i) and (iv) only

Answer 1

Answer: (A)

Equation (1) is Gauss’s law and equation (4) is Ampere’s law and (2) is Gauss law in magnetism. Here three equations are Max well’s equations.
