1. The problem statement, all variables and given/known data Let S be the ellipsoid where a,b, and c are all positive constants. x2/(a+1)+y2/(b2)+z2/(c2) = 1 → → → → → Let F = (r - ai) / ||r - ai|| [* r and i are vectors = I tried inserting the arrows] a)Where is F undefined? b)Find divF at points where divF is defined. c) Find ∫s F dA. 2. Relevant equations Divergence theorem 3. The attempt at a solution I know that the divF=0 making it a divergence free vector field, but I am not sure how to solve for the flux through the ellipsoid. I really would like to understand the actual concept of divergence free theorems and a step by step explanation would really help. Thanks for your time and help!
