ENM — DIPOLES:
Gauss’s Law
Note that this is not actually a law, it’s just a corollary of Coulomb’s Law.
Electric flux through a closed surface is equal to enclosed charge over
- Electric field lines tell you where a positive test charge would go
- Dipole moment points from negative charge to positive charge
- this makes sense, because the general principle is that we give priority to positive dudes and let negative dudes flip signs.
