Hi, I am sort of new to Physics forum but I am urgently in need of help. It would be very much appreciated if you could clear my confusion.(adsbygoogle = window.adsbygoogle || []).push({});

Let me break them down into bullet points instead of one giant paragraph.

1.Dipole moments are vector quantities. I can just add them up like I do to forces?

2. Does dipole have to be composed of 1 positive and 1 negative charge? Can it be two positive charges?

Right now I am trying to compute the dipole moment of a cluster of atoms in a specific shape discretely and then continuously.

3.For the discrete part, I want to know whether if it's correct to treat each pair of atoms(in my case, they are ions+) with a dipole moment with a direction pointing somewhere, and then add them up like vectors of force?

4.For continuous part, I must integrate it over a volume. I don't understand the equation

P(r) = integral of p(r0) (r0 - r) dr^3.

what is p(r0)*(r0 - r)

r0 = r zero = r initial i think?

What if my charge distribution is constant and uniform? Does that mean I can pull it out and times the volume of the shape?

Thank you.
