• Be attracted to the wool cloth

• Be repelled by the wool cloth

• Have no interaction with the wool cloth

• Not enough information is given to determine what will happen

Two pieces of transparent tape are pulled off a wooden tabletop. When they are brought near each other, they:

• Attract each other because they were prepared the same way.

• Repel each other because they were prepared the same way.

• Have no interaction.

When uncharged bits of paper are brought near a charged comb:

• There is no interaction because the paper is not charged.

• There is no interaction because the paper is too heavy to move.

• There is attraction because the paper is a dielectric.

• There is repulsion because the paper is a dielectric.
