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 ?
