Question

can someone help me? Topic: Electrostatics
Question, Two identical, small insulating ball, are suspended by separate 0.250 m threads that are attached to a common point on the ceiling. Each ball has a mass of 8.00 x 10^-4 kg. Initially the balls are uncharged and hang straight down. They are then identical positive charges and, as a result, spread apart with an angle of 36 degree between the threads. Determine the a) charge on each ball, b) the tension in the thread

Answer 3

You can figure all this out by setting up equations for balanced forces.

In the vertical direction, the force of gravity balances the vertical component of the tension force.

In the horizontal direction, the electrostatic force balances the horizontal component of the tension force.

Do you think you could take it from here?
