A student observes interactions between two sets of electrically charged objects. In each set, the objects carry either a charge of –1 or +1 Coulomb. Which question can the student ask to identify the set with the stronger interaction?
A How large are the objects in each set?
How large are the objects in each set?
B How far apart are the objects in each interaction?
How far apart are the objects in each interaction?
C Are the objects both positively charged or both negatively charged?
Are the objects both positively charged or both negatively charged?
D What is the mass of each object in the interactions?
What is the mass of each object in the interactions?
C Are the objects both positively charged or both negatively charged?
The question that can help identify the set with the stronger interaction is B) How far apart are the objects in each interaction?
To identify the set with the stronger interaction, the student can ask the question:
B) How far apart are the objects in each interaction?
Explanation:
The strength of the electric interaction between charged objects depends on the distance between them. The closer the objects are, the stronger the interaction. By asking how far apart the objects are in each interaction, the student can determine which set has a stronger interaction based on the distance between the objects.
