A dipole with a positive charge of 2 μC and a negative charge of -2.0 μC is centered at the origin and oriented along the x-axis with the positive charge located to the right of the origin. The charge separation is 0.0010m. Find the electric field due to this dipole at the point x=4.0m,y=0.0m(k=8.99*10^9Nm^2/C^2)
why the ans here is 0.56i N/C ?? i want a solution thank u :)

this is the same as the last one, with some more fiddling.  i can draw it

you are in the axis of the dipole so you just need to add the fields :)

happy ?!
