Two free protons and two free electrons are separted by the same distance. Compare Coulomb's forces of repulision between the pair of protons and pair of electrons.

What is the mass of proton as compared to electron ?

The ratio of electric force between two electrons to two protons separated by the same distance in air is .

The ratio of electric force between two electrons to two protons separated by the same distance in air is

A proton is nearly 1,836 times more massive than the electron. The Coulomb force of repulsion between two protons separated by a finite distance is F. The electrostatic force between two electrons separated by the same distance is:
