Two identical small insulating balls are suspended by separate0.25-m threads that are attached to a common point on the ceiling. Each ball has a mass of 8.0 x 10-4 kg. Initiallythe balls are uncharged and hang straight down. They are thengiven identical positive charges and, as a result, spread apart with an angle of 36o between the threads. Determine (a) the charge on each ball and (b)the tension in the threads.
