The distance x is measured in meters, while the force is measured in Newton. Graph vour data by plotiing the magnitude of the net force F on the vertical axis, and plotiing the disiarice x on the honzental axis. Do a power fif to vour data points, to determine the mathematical relationship between the net force F and the distance x. Questions: 1. Which of the two point charges that make up the electric dipole has the positive charge? Is it the blue or the red sphere? 2. Write the eguation for the curve that best fits your data points. Does the net force F fall off as the inverse cube of the distance x? 3. What is the value of the numerator 2 k p @ in the numerator of equation (1) abowve?

Introduction In class we solved an example from chapter 21 which asks up to calculate the resultant electric force exerted by an electric dipole on a point charge Q located at a point on the x-axis far away from the electric dipole. The electric dipole consists of a point charge - g located at (xy) = (-0, 0) and another point charge +q located at [x,y) = (g,0). The quantity P = g(2a)i is called the electric dipole moment of the distribution consisting of the two point charges, We showed that the force exerted by the electric dipole on a point charge +Q located on the positive x-axis at (x, 0) far away from the electric dipole (such that x >> a) is given by: F=1232 (1) where k is Coulomb's constant. We noticed in the solution to the example described above, that the electric field generated by the electric dipole at distances far away falls off as the inverse cube of x, that is, as f, and not as the inverse square of the distance. When you add the forces acting on a point charge Q exerted by several point charges, the resultant force experienced by the point charge Q may be different from the inverse square law depending on the orientation, magnitude, and sign of the point charges.
