4. In general, the electric force is directly related to the magnitude (strength) of the charges. This means that as the magnitude of the charges increases, the electric force will also:

A. Increase
B. Decrease
C. Not change at all
D. There is no way to know

5. Therefore, when the magnitude of one charge is increased by a factor, the magnitude of the force will…
A. Increase by the same factor
B. Decrease by the same factor
C. Increase by the square of the factor
D. Decrease by the square of the factor
E. Not change at all

Based on your previous answers, which statement best describes how the electric force would change if the magnitude of Charge 1 were DECREASED?
A. The electric force would decrease.
B. The electric force would increase.
C. The electric force would not change.
D. There is no way to know.

My teacher didn't explain this in her videos

To answer question 4 and question 5, we need to consider the relationship between electric force and the magnitude of charges.

Question 4 asks about the relationship between the electric force and the magnitude of charges. The general rule is that the electric force is directly related to the magnitude of charges. This means that when the magnitude of the charges increases, the electric force increases as well. Therefore, the answer to question 4 is A. Increase.

Question 5 asks how the magnitude of the force changes when the magnitude of one charge is increased by a factor. According to Coulomb's Law, the electric force between two charges is directly proportional to the product of their magnitudes. So, if the magnitude of one charge is increased by a factor, the magnitude of the force will increase by the same factor. Therefore, the answer to question 5 is A. Increase by the same factor.

Now, let's move on to the last question about how the electric force changes when the magnitude of Charge 1 is decreased. Since the electric force is directly related to the magnitude of charges, if the magnitude of Charge 1 is decreased, the electric force will also decrease. Therefore, the answer to the final question is A. The electric force would decrease.

Remember that the magnitude of the charges plays a crucial role in determining the strength of the electric force.

Where are you getting stuck on these questions? In physics, do you know what "directly related" means?
