Consider two charged conductors named A and B. These conductors are identical except for the charge they carry. An ebonite rod, which was charged by rubbing it with fur is brought near each sphere. Conductor A is attracted to it while conductor B is repelled by it. The rod is removed and the two conductors are brought into contact with one another and then separated. The rod is brought back near the conductors and now both are repelled by it....
