a) What does the solenoidal vector field and irrotational vector field mean, what does it mean physically? Show that in a single mathematical expression, a vector field A is solenoidal and irrotational, respectively. b) A solenoidal field vector along the surface integral of a closed surface is equal to 0 to show through the divergence theorem. c) Show by means of the Stokes theorem that the line integral of an irrotational vector field along the closed curve surrounding a surface...
