Hi, I hve kind of a problem with this static electric question; There are two SIMILAR ping pong balls coated with aluminium paint and suspended using nylon string. Taking the imaginary line perpendicular to the wall, on which the balls are hanging from, to be the normal (although this is in light), the ball on the right, W, is at an angle 2x from the normal while the other one, Z, is at an angle x from the normal, after both of them were charged. The question is whther the charge on W is smaller than the charge on Z and the answer is true. However, shouldn't both angles from the normal be equal due to Newton's Third Law; Action = Reaction? Also, does the answer have anything to do with the tension of the string, as I hve read that the greater the angle from the normal, the lesser the tension of the string. I am not rlly sure how to prove this mathematically or using Physics formulas. Any help is greatly appreciated as I'm quite new to this topic. Thanks.
