one charge of +5.0μC is placed in air at exactly x=0, and a second charge +7.0C at x=100cm. Where can a third be placed so as to experience zero net force due to the other two

four equal point charge of +3.0Cμ are placed in air at the four corners of a square that is 40cm apart on a side. Find the force on any of the charge

Three charges are placed at the following locations on the xaxis:+2.0μC at x=0, -3.0μC at x=40cm, -5.0μC at x=120cm. Find (a) on the -3.0μC charge,(b) on the -5.0μC charge.
