To determine the type and amount of electrical force between two charged objects based on the table, it's important to note the behavior of charges. Like charges repel each other, while opposite charges attract.
In this case, both objects have a charge of +1 C. According to the data:
- When the charges are both +1 C and are 4 mm apart, the force is labeled as "medium."
- The observation indicates that as the distance decreases (from 4 mm to 2 mm with like charges), the force increases significantly, indicating it is "strong."
Now, we're looking at a scenario where the two +1 C charges are 10 mm apart. Since this distance is greater than 4 mm, we can infer that the force will still be present but will be weaker than what was observed at 4 mm.
However, since there are no attractive forces between like charges, we conclude that the relationship between the two +1 C objects at 10 mm apart will be repulsive.
Thus, the type of electrical force will be repulsive, and since the existing forces at 4 mm are "medium," we can generally consider that at a greater distance (10 mm), the force will likely be weak.
So, the correct answer is: repulsive, weak.
