Homework Statement



I need to find force between two dipoles. I was thinking of finding F between all the four charges separately and then using superposition principle to get the net charge. but is there an easier way. Say, if I use the formula of E (dipole) for one dipole and multiply it with the charges in another dipole and use superposition principle , will it work?

You can find the fields, and use superposition on the fields, and then multiply by the charge. The field of a dipole and also that of the other charge, that is.

but the question tells me to find net force on a second dipole. so, why do i need to find the field due to the charge in this case? i am even more confused.
