Mr. H inflates a 1.4-gram balloon and charges it negatively by rubbing it on his head. He then rubs a plastic tube with animal fur to impart a charge of -4.3x10-8 C. By holding the plastic tube at a position of 12 cm below the balloon, he is able to levitate the balloon. Consider the two objects to be point charges and determine the quantity of charge upon the balloon.
