Three identical metal balls, A, B, and C are mounted on insulating rods. Ball B is free to slide left and right, so it may touch balls A and C. The balls are surrounded by a Faraday cage which ensures no electrons or electric fields can enter experiment. Initially, ball A has 7 electrons, ball B is uncharged, and ball C has 1 proton (as shown below). leave the system during the B Faraday cage Part A Ball B slides towards, and touches ball A, Ball B then slides right, separating from A, until it touches C. B then separates from C and slides back towards the middle. At the end of the experiment ball C has A B
