Based on the observations in the table, we see that the electric force depends on the charge and distance between the objects. In the given scenario, both objects have a charge of +1 C and are 10 mm apart.
From the table, we can infer:
- Like charges (both positive) result in a repulsive force.
- The strength of the electric force has a correlation with the distance; since no data is provided for a distance of 10 mm, we can extrapolate based on previous observations: the distance of 4 mm showed a medium force, and charges of ±1 C at 2 mm produced a strong force.
Since the distance increased to 10 mm and the charges remain the same, it is likely that the electric force would be weaker than the medium force observed at 4 mm, likely resulting in a weak repulsive force.
Thus, the most likely answer would be: repulsive, weak.
