 Quote by ezperkins 1. The problem statement, all variables and given/known data A point charge of -6 µC is located at x = 1 m, y = -2 m. A second point charge of 12 µC is located at x = 1 m, y = 3 m. (a) Find the magnitude and direction of the electric field at x = -1 m, y = 0. (b) Calculate the magnitude and direction of the force on an electron at x = -1 m, y = 0. 2. Relevant equations 3. The attempt at a solution $$\Sigma_{F}= k\frac{-6 \mu C}{8} + k\frac{12 \mu C}{13} = 1.08e4 \frac{N}{C}$$ That's for the magnitude part of A. I've already submitted to many incorrect responses, but I would like to know how to do it. Thanks ahead of time.
You need to find both the x and y components from each charge at the point of interest and add them up accordingly to find the resultant field.
