The distance needed for electrostatic force between 2 protons can be calculated using Coulomb's Law, which states that the force between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
The unit of measurement for the distance needed for electrostatic force between 2 protons is meters (m).
The strength of the electrostatic force between 2 protons is inversely proportional to the square of the distance between them. This means that as the distance between the protons increases, the force between them decreases.
No, there is no minimum distance for electrostatic force to occur between 2 protons. However, as the distance between them approaches zero, the force between them becomes infinitely large.
The distance needed for electrostatic force between 2 protons is much smaller than the distance needed for gravitational force between the same two protons. This is because the electrostatic force is much stronger than the gravitational force between two particles with the same masses.
