Two identical small insulating balls are suspended by separate0.24-m threads that are attached to a common point on the ceiling.Each ball has a mass of 7.65 10-4 kg. Initially the balls areuncharged and hang straight down. They are then given identicalpositive charges and, as a result, spread apart with an angle of32° between the threads.
(a) Determine the charge on each ball.
C
(b) Determine the tension in the threads.
N
