Okay! I will next time, thank you for the advice. Seems I still have a long way to learn :)

What are the stable orientation(s) for a dipole in an external electric field? What happens if the dipole is slightly perturbed from these orientations?

All the information that I have is these are two opposite sign charge infinite plane with some distance d. I also throw this question to my professor, he suggests me to prove it with Taylor series. But I does not know what variable to setup this with, if anyone have any idea, can you please...

Can someone prove that outside of two infinite planes with opposite charge, the E-field got cancelled? But the between are not.

Can someone explain what is a dipole moment for me? and what it relationship with F and torque?
