Use the table of observations about the electric force between charged objects to answer the question.

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?

attractive, strong
attractive, strong

repulsive, strong
repulsive, strong

repulsive, weak
repulsive, weak

attractive, weak

Answer 1

To analyze the situation, we can refer to the characteristics of electric charges. Like charges repel each other, while unlike charges attract.

In this case, you have two objects each with a charge of +1 C. Since both charges are positive, they will exert a repulsive force on each other.

Now, let's consider the distance: The table shows observations for distances of 2 mm and 4 mm. The relationships we know from the table indicate that:

• At a distance of 4 mm, the electric force between two +1 C charges is described as "medium."
• Similarly, the table does not provide direct data for a distance of 10 mm, but based on typical behavior of electric forces (which usually decrease with the square of the distance), we can infer that the force at 10 mm would be weaker than at 4 mm.

Thus, with this analysis, at a distance of 10 mm between two objects with a charge of +1 C each, the most likely type of force is repulsive and because the distance is greater than that of any observed "medium" interaction, it's reasonable to conclude it would be weak.

Therefore, the answer is:

repulsive, weak
