## What is Coulomb's law write its formula?

Coulomb's Law in Vector Form

Here F_{12} is the force exerted by q_{1} on q_{2} and F_{21} is the force exerted by q_{2} on q_{1}. Force on a charged particle due to a number of point charges is the resultant of forces due to individual point charges i.e. **F ⃗ = F ⃗ 1 + F ⃗ 2 + F ⃗ 3 +** … …

## What is Coulomb's law mathematically?

According to Coulomb's law, the **force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance in between them**. It acts along the line joining up with the two charges thought about to be point charges.Dec 29, 2020

## How do you solve for K in Coulomb's law?

The constant of proportionality k is called Coulomb's constant. In SI units, the constant k has the value. **k = 8.99 × 10 9 N ⋅ m 2 /C 2**. The direction of the force is along the line joining the centers of the two objects.

## What is Coulomb's law class 12?

Coulomb's Law: **The Electrostatic Force of interaction between two static point electric charges is directly proportional to the product of the charges**, inversely proportional to the source of the distance between them and acts along the straight line joining the two charges.
