A student observes interaction between two sets of electrically charged objects, In each set, the object carry either a charge -1 or +1 Coulomb. Which question can the student ask to identify the set with the stinger interaction? Are the objects both positively charged or both negatively charged; What is the mass of each object in the interaction; How large are the objects in each set; How far apart are the objects in each interaction

To identify the set with the stronger interaction between two charged objects, the student should focus on the nature of the charges involved in the interaction.

The relevant question among the options provided would be:

"Are the objects both positively charged or both negatively charged?"

This question is pertinent because:

• If both objects in a set are positively charged (+1 Coulomb), they will repel each other due to like charges.
• If both objects are negatively charged (-1 Coulomb), they will also repel each other.
• If one object is positively charged (+1 Coulomb) and the other is negatively charged (-1 Coulomb), they will attract each other.

The strength of the interaction between charged objects depends on both the magnitude and the sign of the charges. Identifying whether the charges are like (both + or both -) or opposite will help assess the nature of the interaction (attractive or repulsive).

The other questions regarding mass, size, or distance do not directly address the characteristics of the electrical interaction in the context of charge. While distance can affect the force according to Coulomb's Law, the nature of the charges is a more immediate way to identify the stronger interaction.
