Question: The Cartesian components of the electric field in a charge-free region of space are E k = C k + D jk r j ,

The Cartesian components of the electric field in a charge-free region of space are Ek = Ck + Djkrj, where Ck and Djk are constants.

(a) Prove that Djk is symmetric (Djk = Dkj) and traceless (∑k Dkk = 0).

(b) Find the most general electrostatic potential that generates the electric field in part (a).
