Two small conducting balls, each with mass m= 0.22 kg are tied to the ends of non-conducting strings. The strings each have a length of L = 0.28 m. The balls are then each given the same amount of charge, Q=+ 29 nC . Due to Coulomb's law, the balls repel each other, and the system will sit with the balls separated as shown here:
By what distance will the balls be separated (find x)? (You can assume that the angle is very small = small angle approximation; therefore ̘ ∼sin̘ ∼tan ̘ and x ∼ 2̘ L)
The balls will be separated by a distance equal to
