Divergence Theorem?

Question

Prove the identity: The lower bound is "s" ∫ ∫ (a dot n) dS = 0, where a is a constant vector and assuming that "s" satisfys the conditions of the Divergence Theorem

Answer 1

As you know, the Divergence Theorem says

∫ ∫ (a dot n) dS = ∫ ∫ ∫ div a dV

where the triple integral is over the volume enclosed by the surface s. The divergence of a constant vector is zero, right?
