V.K= r² Ər A.6 A.3 Define a physical dipole and its dipole moment. Derive the "far-field" approximation of the electrostatic potential V(r) of a physical dipole situated at the origin, and express it in terms of the dipole moment. You may use = (1 + 2/2F) for |w| << \r\. r±w RINTED: TUESDAY 18TH APRIL, 2017 PAGE 1 Continued overleaf...
