In Coulomb's Law, r represents the distance between the two electric charges. It is also commonly referred to as the "radius of separation."
Coulomb's Law mathematically describes the electrostatic force of attraction or repulsion between two point charges. The formula is:
F = k |q1 q2| / r²
Where:
- F is the electrostatic force
- k is Coulomb's constant
- q1 and q2 are the magnitudes of the charges
- r is the distance between the charges
Therefore, the value of 'r' directly impacts the electrostatic force – as the distance increases, the force decreases proportionally to the square of the distance.
