Consider the electric dipole shown in Figure P23.22. Show that the electric field at a distant point on the +x axis is Ex ≈ 4ke qa/x3.

I tried to get a picture but that didn't work out but it basically shows a positive and a negative charge on the x-axis with a distance of 2a between them.

Not sure how to do this one, it has something to do with finding the x and y components correct?
