Net force between two identical dipoles

Click For Summary
SUMMARY

The discussion centers on calculating the net force between two identical dipoles using the superposition principle. The user initially considers calculating the force between each charge in the dipoles separately but seeks a more efficient method. The consensus suggests utilizing the electric field generated by one dipole and applying it to the charges of the second dipole to determine the net force. This approach simplifies the calculation by focusing on the fields rather than individual charge interactions.

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.
