Question 18 _ " (1 points) Consider two charged conducting spheres separated from each other by air (an insulator). One is large and has a charge of 1 uC, the other is small and has a charge of 2 1:C. Which of the following statements is true if you bring the two spheres intontact so that they touch each other? Select the correct answer Once the two spheres touch, each sphere will have exactly the same charge. The larger sphere will contain all net charge, and the small sphere will have no net charge at all. The electric'potential on both spheres will be exactly the same but not the charges. O O Each sphere will retain its original charge
