Strong Nuclear force

Explanation:

The two arrows indicate what are the forces at play, those forces that keep the protons and neutrons together inside the nucleus of an atom.

Those forces are the strong forces which act a very close distances among particles, and overcome the repulsive electromagnetic force witch repels the protons (positively charged would repel each other)

strong nuclear

Explanation:

the answer to this is proletariats.

hope this : )

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
