WebDavid Griffith's Chapter 2 Section 2-2Calculate the Divergence and Curl of a given Electric Field WebThe second term on the left side is the curl of the curl of the electric field. Now, if E is a central isotropic field, it is of the form E = [xf(r), yf(r), zf(r)] and the x component of the curl of E is . Similarly the y and z components are zero, so the curl of any isotropic central force field (or linear combination of such fields) vanishes. tax preparers in rockwall tx
