[QUOTE="jlmccart03, post: 5679548, member: 606294"] [h2]Homework Statement [/h2] A dipole with charges ±q and separation 2a is located a distance x from a point charge +Q, oriented as shown in the figure. Part A: Find an expression for the magnitude of the net force on the dipole in the limit x≫a. Part B: What is the direction of the net force? Enter answer as number of degrees counterclockwise from the positive x-direction. [ATTACH=full]112311[/ATTACH] [h2]Homework Equations[/h2] F = kq[SUB]1[/SUB]q[SUB]2[/SUB]/r[SUP]2[/SUP] [h2]The Attempt at a Solution[/h2] I honestly cannot think of a solution for this problem. Currently I am stuck on the dipole piece. How does one come up with an equation using the limit x >> a? I guess a better question would be what that means in terms of figuring out the net Force on the dipole. I am simply confused on where to start or how to begin besides using F = kq[SUB]1[/SUB]q[SUB]2[/SUB]/r[SUP]2[/SUP] [/QUOTE]
