Chapter , Problem 26(choose chapter or problem)
There are four charges, each with a magnitude of 2.0 mC. Two are positive and two are negative. The charges are fi xed to the corners of a 0.30-m square, one to a corner, in such a way that the net force on any charge is directed toward the center of the square. Find the magnitude of the net electrostatic force experienced by any charge.
