On Sunday evening when I was lying on bed I was thinking about Coulomb’s law. I didn’t remember what was about this law then I’ve decided to learn more about it:
Yea Coulomb’s law! is interesting that’s why i did simulation of two particles, first was charged with positive charge and second was negative. On image Coulomb’s law from Eulerian view, left side of field is positive charge one right negative.
Particles with different charges, red are positive, blue are negative:

Below we can see Electric Scalar Field and gradient of this function.
