Compute all parts of given question:
Question: Two identical, small insulating balls are suspended by separate 0.26-m threads that are attached to a common point on the ceiling. Each ball has a mass of 7.0 x 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 42o between the threads.
Part A: Determine the charge on each ball?
Part B: Determine the tension in the threads?
This is a physic problem, reply as soon as possible. Thank you.
