2. Show that the electric field of a dipole on its axis points in the direction of dipole moment and on the transverse axis in direction opposite to that of the dipole moment. Further, show that electric field varies inversely as the cube of the distance: assume that the distance of point under consideration is much larger than the separation of charges of a dipole.
An electron is a distance d from a dipole moving along the axis of the dipole, where d is much larger than the separation between the charges of the dipole. At this point, the magnitude of the force on the electron is 6e-8N. the electron moves a distance 3d from the dipole. What is the new magnitude of the force on the electron due to the dipole at this point? --The answer is F= 2.2x10-9but I don't understand how to...
6. Electric dipole is a system of two (+ and -q) charges located at distance d from each-other. A charged particle is located at a point on an electric dipole axis. The distance between the particle and the dipole center is r. Which describes the force on the charge proportional to the distance if r is much larger in comparison with the dimension of the dipole d? r3
(a) Two point charges are a distance d apart along the y-axis. Find the electric field (magnitude and direction) at any point in the y=0 plane when the charges are: i) 91 = 9, 92 = 0 ii) both equal 91 = 92 = 9 iii) of opposite polarity but equal magnitude 9ı = -92 = 9. This configuration is called an electric dipole with dipole moment p, = qd. (b) For each of the 3 cases in (a) find...
