When building and testing the electric force with the electroscope, what caused the tin foil leaves to move?

• When moving the charged rod close to the electroscope, the negative forces on the rod repelled the negative forces onto the leaves and caused them to move.

• When moving the charged rod close to the electroscope, the negative forces on the rod attracted the negative forces on the leaves and caused them to move.

• When moving the charged rod close to the electroscope, the negative forces on the rod attracted the positive forces onto the leaves and caused them to move.

• The negatively charged rod touched the metal tin on the electroscope, pushing positive charges down to the leaves
