Question

A negative charge of 0.00044C and a positive charge of 0.00072C are separated by 0.59 m. What is the force between the two charges?

 

- \( F = k \cdot \frac{q_1 q_2}{r^2} \) - \( k = 9 \cdot 10^9 \, \text{N} \cdot \frac{\text{m}^2}{\text{C}^2} \) **Explanation:** These equations are related to electrostatics: 1. **Coulomb's Law**: The first equation represents Coulomb's law, which describes the force (\( F \)) between two point charges (\( q_1 \) and \( q_2 \)). The force is directly proportional to the product of the magnitudes of the charges and inversely proportional to the square of the distance (\( r \)) between them. The constant of proportionality is \( k \), known as Coulomb's constant. 2. **Coulomb's Constant**: The second line defines the value of Coulomb's constant (\( k \)), which is \( 9 \times 10^9 \, \text{N} \cdot \frac{\text{m}^2}{\text{C}^2} \). This constant is used to calculate the force in the International System of Units (SI).
