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)
Responses
Are the objects both positively charged or both negatively charged?
Are the objects both positively charged or both negatively charged?
How large are the objects in each set?
How large are the objects in each set?
How far apart are the objects in each interaction?
How far apart are the objects in each interaction?
What is the mass of each object in the interactions?
The question the student can ask to identify the set with the stronger interaction is: "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)
Responses
+2 C
+2 C
+1 C
+1 C
–2 C
–2 C
–1 C
The object with which charge would be most strongly attracted by object A is: +2 C
Use the table of observations about the electric force between charged objects to answer the question.
Charge of Object 1 (C) Charge of Object 2 (C) Distance (mm) Amount of Electric Force
+1 +1 4 medium
–1 –1 2 strong
–2 +2 4 strong
An object with a charge of +1 C is 10 mm from an object with a charge of +1 C. Based on the data in the table, which type and amount of electrical force will there most likely be between the two objects?
repulsive, weak
attractive, strong
attractive, weak
repulsive, strong

Based on the data in the table, the most likely type and amount of electrical force between the two objects (one with a charge of +1 C and the other also with a charge of +1 C) is repulsive, weak.
How does the magnitude of the electrical charge on objects affect the electric force between them?(1
As the charge increases, the force increases in strength.
As the charge increases, the force decreases in strength.
As the charge increases, the force becomes more negative.
As the charge increases, the force becomes more attractive.
As the charge increases, the force increases in strength.
