Two identical insulating balls are suspended by a seperate 0.25m threads that are attached to a common point on a ceiling. Each ball has a mass of 8.0 x 10E-4 Kg. At first the balls are uncharged and hang straight down. They are given identical positivecharges and as a result spread apart with an angle of 36 degrees between the threads. Determine a) the charge on each ball and b) the tension in the threads.
