The charge on each ball and the tension in the threads

Reference no: EM13560918

Two identical small insulating balls are suspended byseparate 0.25-m threads that are attached to a common point on theceiling. Each ball has a mass of 8.0 × 10-4 kg.Initially the balls are uncharged and hang straight down. They are then given identical positive charges and, as a result, spreadapart with an angle of 36° between the threads. Determine

a) the charge on each ball and
b) the tension in the threads.
