Statement of a problem № 10676


Two identical small insulating balls are suspended by separate 0.25-m threads that are attached to a common point on the ceiling. Each ball has a mass of 8.0 × 10-4 kg. Initially the balls are uncharged and hang straight down. They are then given identical positive charges and, as a result, spread apart with an angle of 368 between the threads. Determine (a) the charge on each ball and (b) the tension in the threads.
