- ta p3 d. The aim of the remaining exercise is to show a specific version of Gauss' theorem rds so if the origin is outside S I= 47 if the origin is inside S with the help of the guidance steps below. (i) Use the divergence theorem to show that the first statement, I = 0 if the origin is outside S. is true. (ii) To prove the second statement involves two steps for which you will need a sphere Sro, of radius ro, centred at the origin. One of the steps uses the result of the first statement and for the other you will need to do a specific computation
