To determine the type and amount of electric force between an object with a charge of +1 C and another object with a charge of +1 C at a distance of 10 mm, we must first consider the nature of the charges.
Since both objects have a charge of +1 C, they have the same type of charge. According to Coulomb’s law, like charges repel each other.
From the observations in the table you provided, we can see that:
- The force is strong between two charges of the same sign at a distance of 2 mm (e.g., -1 and -1 C).
- A charge of -2 C and +2 C at a distance of 4 mm also exerts a strong force.
While the distance in your scenario is 10 mm (which wasn't directly tested in the provided observations), we can infer based on charge interactions that:
- The force will be repulsive since both charges are +1 C.
- The amount of force can still be considered strong because of the significant magnitude of the charges, albeit the exact value might decrease with increased distance.
Therefore, the most appropriate response is: repulsive, strong
