Use the divergence theorem to show that

[tex]\int\int_S \hat{\mathbf{n}}\,dS=0,[/tex]

where [tex]S[/tex] is a closed surface and

[tex]\hat{\mathbf{n}}[/tex] the unit vector

normal to the surface [tex]S[/tex].

How should I understand the l.h.s. ?

Coordinatewise? The r.h.s. is not 0, but zero vector?
