Answer 1

To identify the set with the stronger interaction between two charged objects, the student should ask: "How far apart are the objects in each interaction?"

The strength of the electrical interaction between charged objects is influenced by the distance between them according to Coulomb's law, which states that the force between two charges is inversely proportional to the square of the distance between them. Thus, knowing the distance will help determine the strength of the interaction.

While the charges themselves (whether +1 or -1 Coulomb) will also impact the interaction strength (opposite charges attract, like charges repel), the question of distance directly pertains to the magnitude of the interaction force. Other questions about the size or mass of the objects don't directly affect the charge interaction in this context.
