nope but i actually found the mistake for the tension, it was in my calculations. but the third part of the question ask to find the chrage on the balls. since i found the electric force acting on the balls after i found tension...do i use the Coulombs law?

yea i am but how would i put that in there since they did not give my any charges...

Two small plastic balls hang from threads of negligible mass. Each ball has a mass of 0.200 and a charge of magnitude q. The balls are attracted to each other, and the threads attached to the balls make an angle of 20.0 with the vertical, as shown in the figure...
