In the ever popular game from the future, Electrodisc, players can score double points by pushing a disc into another disc with the electric field generated by a third disc. The discs are by regulation 1 kg. All discs have the same shape and are made of the same conducting material. In the figure below (a top down view), the discs are all lying on a surface with negligible friction. Disc 1 is permanently held stationary by an insulator (not shown). Disc 2 is temporarily held in place with an insulator (not shown) by the player. The center of disc 2 is 2.5 m from disc 1. Disc 3 is initially motionless but free to move. The player then removes the restraining insulator from disc 2, allowing it to move freely. 10 m F2 What is the initial magnitude of the acceleration imposed on the second disc? The charge on the first disc is 1.5 mC. The charge on the second disc is 1.1 mC. The charge on the third disc is neutral. (You may assume polarization effects are negligible, and the discs behave like point charges.) m/s Later, discs 2 and 3 touch and charge is exchanged. How much charge is exchanged once the charges on each disc reach equilibrium? mC After charge is exchanged, what is the direction of the force on disc 3 due to disc 2?
