A point charge of +Q is placed at the center of a square and asecond point charge of -Q is placed at the upper left corner. It isobserved that an electrostatic force of 2.0 N acts on the positivecharge at the center.
What is the magnitude of the force that acts on the center charge if a third charge of -Q is placed at the lower left corner?
