To determine the type of interaction between the particles in each scenario, we need to understand the concept of electric charges. Electric charges can be positive or negative, and they can either attract or repel each other.
1. Two positive charges placed close together: In this scenario, both charges have the same positive sign, so they will repel each other. Therefore, the correct match is "d. Weak repulsive interaction."
2. Two negative charges placed far apart: Since both charges are negative, they will also repel each other. In this case, since they are far apart, the repulsive interaction will be weak. Therefore, the correct match is "d. Weak repulsive interaction."
3. A negative charge and a positive charge placed close together: Positive and negative charges have opposite signs, so they will attract each other. When they are placed close together, the attractive interaction will be strong. Therefore, the correct match is "c. Strong attractive interaction."
4. A negative and a positive charge placed far apart: Similarly, the negative and positive charges will attract each other due to their opposite signs. However, when they are far apart, the attractive interaction will be weak. Therefore, the correct match is "b. Weak attractive interaction."
In summary:
1. Two positive charges placed close together: d. Weak repulsive interaction
2. Two negative charges placed far apart: d. Weak repulsive interaction
3. A negative charge and a positive charge placed close together: c. Strong attractive interaction
4. A negative and a positive charge placed far apart: b. Weak attractive interaction
