To analyze the situation:
- The charges of both objects are +1 C.
- Since both objects have the same type of charge (positive), they will repel each other according to Coulomb's law.
- The distance between the two objects is 10 mm, which is greater than the distance values given in the table (4 mm and 2 mm).
In the data from the table:
- The force is described as "medium" for two +1 C charges at a distance of 4 mm.
- For two oppositely charged objects (–1 and –1 C), the force is "strong" at 2 mm.
- A strong force is also recorded for two charges of opposite signs (–2 and +2) at a distance of 4 mm.
Since the distance (10 mm) is greater than the previously observed distances, it can be inferred that the force would be weaker than "medium" for the 4 mm distance.
Therefore, the likely conclusion based on the given information is:
repulsive, weak
