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= F_{e}/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?
