HI! Today lets talk about COULOMB’S LAW. In my blog let’s try to learn about the concepts of it. Take time to read it and let’s learn from one another! Have a good day!

WHAT I KNEW?

Honestly, i am not this kind of familiar with this topis just because it’s my first time to encounter it. In our discussion i understood and gain knowledge in connection with the concepts VECTOR and SCALAR QUANTITY.

WHAT I LEARNED?

First, let’s defined COULOMB’S LAW…

- Coulomb’s law, or Coulomb’s inverse-square law, is a law of physics for quantifying the amount of force with which stationary electrically charged particles repel or attract each other.
- Which is the force of attraction or repulsion acting along a straight line between two electric charges is directly proportional to the product of the charges and inversely to the square of the distance between them.

Here is the formula of ELECTROSTATIC FORCE:

where ke is Coulomb’s constant (ke ≈ 9×109 N m2 C−2), q1 and q2 are the signed magnitudes of the charges, and the scalar r is the distance between the charges. The force of the interaction between the charges is attractive if the charges have opposite signs (i.e., F is negative) and repulsive if like-signed (i.e., F is positive)..

FORCE AS A VECTOR QUANTITY

The electrical force, like all forces, is typically expressed using the unit Newton. Being a force, the strength of the electrical interaction is a vector quantity that has both magnitude and direction.
