Sry, I thought of one charge on the origin and the other at +d. But it's better to put the charges on -d/2 and d/2 of course.
And I used the x-z plane, so this might be confusing, sry for that.
Thanks, this helped also a lot for my understanding. Taylor expansion is something I learned but I'm...
Thanks for your reply. I see now what my problem was. I had only one component because I just looked for the field on the y-axis that its exactly on x=d/2. So in the exact mid of the two charges with respect to the x-axis. So I just didn't calculated the complete field for every point on the...
Hi everybody. I noticed that I don't understand dipoles correctly. I just calculated the field of a dipole. There are two charges, one positive the other negative, in the distance of d.
I got for the electric field: E=\frac{q}{4 \pi \epsilon} \binom{d}{0} The problem is, that there is only the...
