Which one of the following Maxwell's equations implies the absence of magnetic monopoles?
1
\(\oint{\vec{E}\centerdot d\vec{s}=\frac{{{Q}_{enclosed}}}{{{\varepsilon }_{0}}}}\)
2
\(\oint{\vec{B}\centerdot d\vec{s}=0}\)
3
\(\oint{\vec{E}\centerdot d\vec{l}}=-\frac{d}{dt}\int{\vec{B}.d\vec{s}}\)
4
\(\oint{\vec{E}\centerdot d\vec{l}}={{\mu }_{0}}I+{{\mu }_{0}}{{\varepsilon }_{0}}\frac{d}{dt}\int{\vec{E}.d\vec{s}}\)
