An electric dipole consists of two point charges of equal magnitude but opposite polarity, separated by a distance d [Fig. 4-13(a)]. Determine V and E at any point P. given that P is at a distance Rd from the dipole center, and the dipole resides in free space. +ge d qe 07 R R d cos 0 R (a) Electric dipole P = (R, 0, 0) -y
