Responses
Interaction C
Interaction B
Interaction A and B
Interaction C and D
The correct answer is Interaction C, because when two objects have charges with the same sign (in this case both are positive), they will repel each other. Therefore, Interaction A and D will have a repulsive electrical force, while Interaction B has no net electrical force since the charges are equal in magnitude and opposite in sign. Interaction C, with one positively charged object and one negatively charged object, will have an attractive electrical force.
Well, isn't it shocking that I have to give a serious answer for this question about electrical forces? But don't worry, I'll still try to spark some humor! Now, let's take a closer look at the data set.
In order for a force to be attractive, the objects must have charges of opposite signs. So, which interactions fit the bill? Well, Interaction C has two charges of the same sign, so that won't attract anything. Interaction D also has two charges of the same sign, which means it won't be attracting either.
So, what about Interaction A and B? Well, in Interaction A, we have a positive charge and a negative charge. That's like a magnetic attraction between a happy proton and a grumpy electron - they just can't resist each other! Moving on to Interaction B, we have two charges of the same sign, which we just established won't attract each other.
Therefore, the correct answer is Interaction A and B. So, those positive and negative charges are just pulling each other closer like two magnets on a refrigerator door. I guess opposites really do attract!
To determine which interactions will have an attractive electrical force, we need to look at the charges of the objects involved.
An attractive electrical force occurs when the charges of the two objects have opposite signs.
Looking at the data set:
Interaction A: Object 1 charge is +4 and Object 2 charge is -3 (opposite signs), so this interaction will have an attractive electrical force.
Interaction B: Object 1 charge is +1 and Object 2 charge is -1 (opposite signs), so this interaction will have an attractive electrical force.
Interaction C: Object 1 charge is +1 and Object 2 charge is +1 (same signs), so this interaction will have a repulsive electrical force, not an attractive force.
Interaction D: Object 1 charge is -1 and Object 2 charge is -1 (same signs), so this interaction will have a repulsive electrical force, not an attractive force.
Therefore, the correct answer is:
Interaction A and B
To determine which interactions will have an attractive electrical force, we need to understand the basic principle of electrical forces. The electrical force between two charged objects can be attractive or repulsive, depending on the charges of the objects.
According to Coulomb's Law, like charges repel each other and opposite charges attract each other. So, if the charges of two objects are the same, the electrical force between them will be repulsive. On the other hand, if the charges of two objects have opposite signs, the electrical force between them will be attractive.
Now let's analyze each interaction from the given data set:
Interaction A: Object 1 has a charge of +4 and Object 2 has a charge of -3. Since the charges have opposite signs, this interaction will have an attractive electrical force.
Interaction B: Object 1 has a charge of +1 and Object 2 has a charge of -1. Again, the charges have opposite signs, so this interaction will have an attractive electrical force as well.
Interaction C: Object 1 has a charge of +1 and Object 2 has a charge of +1. Both charges are positive, so this interaction will have a repulsive electrical force, not an attractive force.
Interaction D: Object 1 has a charge of -1 and Object 2 has a charge of -1. Both charges are negative, so this interaction will also have a repulsive electrical force.
Based on this analysis, the correct answer is: Interaction A and B.
