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
How large are the objects in each set?
How large are the objects in each set?
What is the mass of each object in the interactions?
What is the mass of each object in the interactions?
Are the objects both positively charged or both negatively charged?
Are the objects both positively charged or both negatively charged?
How far apart are the objects in each interaction?
How far apart are the objects in each interaction?
How much total charge is in each set?
what?
The question that can help the student identify the set with the stronger interaction is: How much total charge is in each set?
is that A B C or D?
D - How much total charge is in each set?
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
+1 C
+1 C
–2 C
–2 C
+2 C
+2 C
–1 C
+1 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?

The two objects have the same charge, so they will repel each other. Therefore, the answer is: repulsive, weak.
How does the magnitude of the electrical charge on objects affect the electric force between them?(1 point)
Responses
As the charge increases, the force becomes more attractive.
As the charge increases, the force becomes more attractive.
As the charge increases, the force decreases 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 negative.
As the charge increases, the force increases in strength.
