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? (1 point)
• Are the objects both positively charged or both negatively charged?
• How large are the objects in each set?
• How far apart are the objects in each interaction?
• What is the mass of each object in the interactions?
• How far apart are the objects in each interaction?
Object A has a charge of -1 Coulomb. At a given distance, the object with which charge would be most strongly attracted by object A? (1 point)
• +2 C
0 +1 C
0 -2 C
0 -1 C
