Coulomb's Law describes the force between two charged objects. It states that the electrostatic force between two point charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. In simple terms, it tells us how strong the attraction or repulsion is between two charges.
The formula for Coulomb's Law is:
\[
F = k_e \cdot \frac{|q_1 \cdot q_2|}{r^2}
\]
Where:
Key points to remember:
Coulomb's Law helps explain how charges interact with each other in electrostatic fields.
The formula for Coulomb's Law is:
\[
F = k_e \cdot \frac{|q_1 \cdot q_2|}{r^2}
\]
Where:
- \( F \) is the force between the charges (in Newtons),
- \( k_e \) is Coulomb’s constant (\( 8.99 \times 10^9 \, \text{N} \cdot \text{m}^2/\text{C}^2 \)),
- \( q_1 \) and \( q_2 \) are the magnitudes of the two charges (in Coulombs),
- \( r \) is the distance between the charges (in meters),
- The absolute value (|...|) ensures the force is always positive, meaning it's either attractive or repulsive, depending on the sign of the charges.
Key points to remember:
- Attractive Force: If the charges are opposite (one positive and one negative), the force is attractive.
- Repulsive Force: If the charges are the same (both positive or both negative), the force is repulsive.
