Problem there are four charges each with a magnitude of 20, Ask an Expert

Academics

Problem: There are four charges each with a magnitude of 2.0 Î¼C. Two are positive and two are negative. The charges are fixed to the corners of a 0.30-m square, one to corner, in such a way that the net force on any charge is directed toward the center of the square.

Part A: Find the magnitude of the net electrostatic force experienced by any charge.

I don't just need an answer, work and explanations/walkthrough would be much appreciated! Thanks.
