Two identical small insulating balls are suspended by separate 0.23-m threads that are attached to a common point on the ceiling. Each ball has a mass of 8.70 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 34° between the threads.
Determine the charge on each ball.
Determine the tension in the threads.
