Question

The Maxwell's four equations are written as
(i) $∫Eâ‹\dots ds=q/{Î\mu }_0$
(ii) ${∫}_{S}Bâ‹\dots ds=0$
(iii) ${∫}_{S}Eâ‹\dots dl=−\frac{d}{dt}{∫}_{s}Bâ‹\dots ds$
(iv) $∫Bâ‹\dots dl={μ}_{0}I+{μ}_0{Î\mu }_0\frac{d}{dt}{∫}_{s}Eâ‹\dots ds$
The equation which have sources of $E$ and $B$ are

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

Answer 1

Answer: (D)

Equation (i) is Gauss's law and equation (iv) is Ampere's law Here, two equations are Maxwell's equations.
