Like charges on two identical balls

Ask Custom Question

Two identical metal balls bear the same amount and sign of electric charge because they have been touched together. The mass of each ball is 2.00 grams. One ball is mounted on an insulating post. The other ball is suspended from a bifilar silk thread suspension system so that it can move on a 0.500 meter radius. When the two balls are 0.0500 meters from each other in the same horizontal plane, the suspension makes an angle of 30.0 degrees from the vertical. What is the charge (in Coulombs) on either of the balls? (I have drawn a picture of the apparatus, but I'm not sure if it is correct - how can they be in the same horizontal plane @ 30 degrees and still swing and touch?)

The way to imagine it is two put them both on the same horizontal plane, that is when you see them from the side, you see one ball on the pole, and the other one suspended at its side, by a thread, so that both balls are on the same height, but the free one is ...
