Two objects carry initial charges that are q1 and q2, respectively, where uq2u . uq1u. They are located 0.200 m apart and behave like point charges. They attract each other with a force that has a magnitude of 1.20 N. The objects are then brought into contact, so the net charge is shared equally, and then they are returned to their initial positions. Now it is found that the objects repel one another with a force whose magnitude is equal to the magnitude of the initial attractive force. What are the magnitudes of the initial charges on the objects?

Let's say two unknown charges are given to you. You do not know their individual charges, but you know that their total charge is 8.00µC. You made a test in the laboratory and found that these two charges push each other away with a force of 0.150 N when separated by 0.500 m. What is the charge of the "higher charge" in units of µC ?
There are four charges, each with a magnitude of 2.0 mC. Two are positive and two are negative.
