Two Q = +5.86 mC charges are placed at opposite corners of a square d = 0.9 m on each side, and -Q = -5.86 mC charges are placed at the remaining corners.
Determine the magnitude and direction of the force on each charge.
The Attempt at a Solution
My teacher just gave this to us without any explanation of how to go about solving such a problem. I have a basic understanding of electric fields and I know coulomb's law, can someone please help me work through this? I'm wondering if this is at all similar to the problems where the charges are simply placed on a horizontal plane with a set distance between two charges. I know how to solve those problems, but I'm not sure if you use the same strategy to solve this problem.
Thanks in advance
