Coulomb's Law
Coulomb's Law describes the electrostatic force between two charged objects. It states:
* The force is directly proportional to the product of the charges.
* The force is inversely proportional to the square of the distance between the charges.
Formula:
F = k * (q1 * q2) / r²
Where:
* F is the electrostatic force (in Newtons)
* k is Coulomb's constant (approximately 8.98755 × 10⁹ N⋅m²/C²)
* q1 and q2 are the charges of the two particles (in Coulombs)
* r is the distance between the centers of the two charges (in meters)
Calculation:
1. Identify the values:
* q1 = 8.0 x 10⁻⁶ C
* q2 = 8.0 x 10⁻⁶ C
* r = 0.6 m
2. Plug the values into the formula:
F = (8.98755 × 10⁹ N⋅m²/C²) * (8.0 x 10⁻⁶ C * 8.0 x 10⁻⁶ C) / (0.6 m)²
3. Calculate the force:
F ≈ 160 N
Therefore, the force between the two particles is approximately 160 Newtons.
Important Note: Since both charges are positive, the force between them is repulsive. This means the particles will push each other away.
