Question

coulombs law in vector form

Answer 1

Coulomb’s Law gives an idea about the force between two point charges. By the word point charge, we mean that in physics, the size of linear charged bodies is very small as against the distance between them. Therefore, we consider them as point charges as it becomes easy for us to calculate the force of attraction/ repulsion between them.

Vector Form of Coulomb’s Law

The physical quantities are of two types namely scalars (with the only magnitude) and vectors (those quantities with magnitude and direction). Force is a vector quantity as it has both magnitude and direction. The Coulomb’s law can be re-written in the form of vectors. Remember we denote the vector “F” as F, vector r as r and so on.

Answer 2

Coulomb's Law is one of the basic ideas of electricity in physics. The law looks at the forces created between two charged objects. As distance increases, the forces and electric fields decrease. The force between the objects can be positive or negative depending on whether the objects are attracted to each other or repelled.  

When you have two charged particles, an electric force is created. If you have larger charges, the forces will be larger. It's a formula that measures the electrical forces between two objects.

F=kq1q2/r2

"F" is the resulting force between the two charges. The distance between the two charges is "r" also known as radius of seperation  

The "q1" and "q2" are values for the amount of charge in each of the particles and K is constant
