Coulombs equation

[JustinHorriat_4f]

Can someone explain coulombs equation to me?
It says F(e)=(kQ1Q2)/r^2

[Jacob Motawakel]

the force of attraction between two atoms is the absolute value of the product of the charges of the two atoms divided by the distance from each nucleus squared.

I also answered this on another person's post, but basically, Coulomb's equation measures the electrostatic force between two charged particles. The particles must be stationary for the equation to be accurate (that's why the measured force is called electroSTATIC). The greater the charge of the particles (q1 and 12), the greater the electrostatic force. The greater the distance between the particles (r), the smaller the electrostatic force.

Coulomb's law describes the force between two charged particles. This Coulomb force is extremely basic, since most charges are due to point-like particles. It is responsible for all electrostatic effects and underlies most macroscopic forces. This equation is given by F(e)=(kQ1Q2)/r^2 (unit in Newtons)

To put it concisely, Coulomb's equation gives you the relationship between electrostatic charge and radius (or distance) between ions. Hope this helps!
