I'm having trouble understanding these kinda questions. I'm assuming this kinda thing applies to all types of force when there's 3 objects exerting the force so its fairly important to know. Let's say I have 3 charges of 11x10-6C that make up an equilateral triangle.

I've calculated the force of repulsion between 2 of these charges and its 48.4N. I don't really know what to do from here on. I can see that the x components of forces AB and AC cancel each other out and their y components add to 83.8N. Does that mean the net force acting on each of these 3 charges is 83.8N?
Also when it comes to things like these is it just a matter of knowing the x and y components involved then using them to get the resultant?
