WebSep 8, 2016 · I am also directed to use Green's second identity: for any smooth functions f, g: R3 → R, and any sphere S enclosing a volume V, ∫S(f∇g − g∇f) ⋅ dS = ∫V(f∇2g − g∇2f)dV. Here is what I have tried: left f = ϕ and g(r) = r (distance from the origin). Then ∇g = ˆr, ∇2g = 1 r, and ∇2f = 0. Note also that ∫Sg∇f ⋅ dS = r∫S∇f ⋅ dS = 0.
