Coulomb's Law is a fundamental law in physics that describes the interaction between charged particles. It states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Coulomb's Law can be extended to apply to 3 charges by using vector addition. The total force between the three charges is the vector sum of the individual forces between each pair of charges.
The formula for Coulomb's Law is F = k(q1q2/r^2), where F is the force between two charges, q1 and q2 are the charges of the particles, r is the distance between them, and k is the Coulomb constant (8.99 x 10^9 Nm^2/C^2).
Yes, Coulomb's Law applies in 3 dimensions. The distance between the charges must be measured in 3D space and the force between the charges will also have a 3D direction.
Coulomb's Law has many real-world applications, such as in the design of electronic devices, the behavior of atoms and molecules, and the study of electromagnetic fields. It is also used in the development of technologies like batteries, capacitors, and electric motors.
