Hi. I know this group is for sharing resources but I need
some help from human resources.  Being a novice high school
Physics teacher, I've come across some problems with those
pesky positive and negative signs with Coulomb's Law.
Would I say to the students that two unlike charges experience
an attractive force of -1 N (for example) or +1 N. Can the magnitude
of ANYTHING have a negative sign in front of it? Thanks for any
information. I appreciate it. Marsh Carroll
