Expert Answer. 4. Prove that for an arbitrary vectoru: (X) 0 (In fluid mechanics, where u is the velocity vector, this is equivalent to saying that the vorticity [the curl of the velocity] is a solenoidal vector field [divergence free]. It is very useful in manipulating the equations of motion, particularly at high Reynolds numbers)A qualitative picture of the electric field distribution within conductors emerges from arguments similar to those used in Sec. 6.5 for linear dielectrics.
