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?
Coulonmb's law ( Felectric= kC(q1*q2)/r^2
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.
