WebMar 12, 2024 · Its obvious that if the curl of some vector field is 0, there has to be scalar potential for that vector space. ∇ × G = 0 ⇒ ∃ ∇ f = G This clear if you apply stokes theorem here: ∫ S ( ∇ × G) ⋅ d A = ∮ C ( G) ⋅ d l = 0 And this is only possible when G has scalar potential. Hence proved.
