1. Homework Statement
Three charges are arranged as shown in the picture I attached. Find the magnitude and direction of the electrostatic force on the charge at the origin.
2. Homework Equations
I know that Coulomb's Law must be applied.
3. The Attempt at a Solution
I've drawn a force diagram with F_{CB} pointing to the left and F_{AB} pointing down. I've also broke the vectors into components using Coulomb's Law and added them together. By doing this, I got 2.7 x 10^{5} [itex]\hat{x}[/itex] + 0 [itex]\hat{y}[/itex]. From here what do I do to get an answer?
I know the answer is supposed to be 1.38 x 10^{5} at 77.5 degrees so I need help with how to get there.
