You have a pair of cannon balls, each 100kg in mass, and a ‘charge shuttling’ device which can be used to remove electrons from one object and place them on another. One of the cannon balls is suspended from the ceiling with an insulating cord. You want to use electrostatic attraction to cause the other to hang in space beneath it, just by removing electrons from the upper cannon ball, and placing them on the lower one. How many electrons must you “shuttle” in order to get the lower cannon ball to hover 2.0m below the upper one? Give your answer in moles.
