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?

(1 point)

attractive, weak

O attractive, strong

O repulsive, strong

repulsive, weak

Answer 1

To determine the type and amount of electrical force between two charged objects using the information given, we can refer to Coulomb's Law, which states that the electric force between two point charges is given by the formula:

\[ F = k \frac{|q_1 \cdot q_2|}{r^2} \]

where:
- \( F \) is the electric force,
- \( k \) is Coulomb's constant,
- \( q_1 \) and \( q_2 \) are the magnitudes of the charges, and
- \( r \) is the distance between the charges.

In this case:
- Charge of Object 1 (\( q_1 \)) = +1 C
- Charge of Object 2 (\( q_2 \)) = +1 C
- Distance \( r \) = 10 mm = 0.01 m

Since both charges are positive, they will repel each other, leading to a repulsive force between them.

Now, according to the distances and strength of forces indicated in the table:
- For charges of +1 C and +1 C at a distance of 10 mm, the force would be considered **strong** due to the high magnitude of the charges involved and the relatively small distance between them.

Therefore, the correct answer is:

**repulsive, strong**
