1. The problem statement, all variables and given/known data Two equal but oppositely charged points are 1.0 m apart in a vacuum. The electric field intensity at the midpoint between the charges is 2.4x10^5 N/C. What is the magnitude of each charge? 2. Relevant equations Electric force= Kc (q/r^2) Kc=8.99x10^9 3. The attempt at a solution Hi guys, first off, thanks for any help given. My problem is that I am unsure as to how to incorporate both missing charges into the equation. I tried solving the equation simply by putting in what is given. 2.4 x 10^5 = 8.99x10^9(q/1^2) 2.4x10^5=8.99x10^9 x q q= .000027 Thus, I only found one charge, and I don't even believe that is right.. Could someone help explain what I am to do? Thanks for the help!
