1. The problem statement, all variables and given/known data Two point charges are 10.0 cm apart and have charges of 2.0 uC ( the u is supposed to be a greek symbol where the left side of the u is extended down) and -2.0 uC, respectively. What is the magnitude of the electric field at the midpoint between the two charges? 2. Relevant equations Coulonmb's law ( Felectric= kC(q1*q2)/r^2 3. The attempt at a solution I have absolutley no idea how to figure this one out. My text book has left me high and dry on this one. The only thng that I dd that makes any sense at all is: Felectric= 8.99*10^-9(-4/100) = -3.6*10^-10 I need some serious help with this. I would appreciate it if someone showed me how to figure this thing out.
