E = k | Q 1Q 2 | r 2. Where: E = Electric Field at a point. k = Coulomb's Constant. k = 8.98 ∗ 10 9 N ∗ m 2 C 2. r = Distance from the point charge. Q1 = magnitude of the first Charge. Q2 = magnitude of the second Charge. Beside this formula, you could speed-up the calculation process with a free electric potential calculator that. To find the total electric field due to these two charges over an entire region, the same technique must be repeated for each point in the region. This impossibly lengthy task (there are an infinite number of points in space) can be avoided by calculating the total field at representative points and using some of the unifying features noted next.
