1. The problem statement, all variables and given/known data Question: An electron and a proton are fixed at a separation distance of 925nm. Find the magnitude and direction of the electric field at their midpoint. 2. Relevant equations E= Fe/q 3. The attempt at a solution (8.988 x 10^9) x (q/(9.25 x 10^-7)2) This is the equation i have to solve for it but I don't know what q is in this situation. Help?
