Two identical small insulating balls are suspended by separate 0.22-m threads that are attached to a common point on the ceiling. Each ball has a mass of 8.10 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 38° between the threads.

a) Determine the charge on each ball. UNITS IN C

b) Determine the tension in the threads. UNITS IN N
