Atomic nuclei would fly apart
Then there would be no atoms - except for hydrogen. The protons would push each other away because they have the same charge (this would not affect hydrogen, since hydrogen has only a single proton in its nucleus).
There are four basic forces in nature, that we know of. The electromagnetic force is one of these. Another is gravity. Two others, the strong nuclear force, and the weak nuclear force, are important, but people do not notice them much.
Without all of these forces, all nature would be entirely different. Without the electromagnetic force, no physical thing we know of would exist.
then the person will fall and not move, staying stationary and stop moving
nuclear weapons and reactors would be impossible.
Atoms would explode...
well thats easy, it would fly away from the sun in a straight line.
The electric force has a longer range. The strong force, as the name implies, is strong, however, it only works for a short range, namely, the range of the nucleus.
The force of "strong force" increases with distance, unlike gravity and electromagnetism which do the opposite.
A repulsive force would exist as like charges always repel each other.
Gravity, electromagnetic, strong nuclear, weak nuclear.
it could not exist
-- gravity -- electrostatic force -- weak nuclear force -- strong nuclear force
the particles would all become de-localised, and no elements would exist, just sub-atomic particles.
Between protons and neutrons exist the residual strong force (nuclear force).
Without the strong force atoms would fly apart and nothing would exist as we know it.
The nucleus would fly apart.
It's to do with the intermolecular bonds (the van Der Waals forces). If they are strong, the substance exists as a solid as the particles are held together with a strong force. If however they are weak, the substance will be a gas.
The "strong nuclear" force, but this can only happen if there are also neutrons, as the "electromagnetic" force would usually repel two protons.
The strongest force known is called the "strong force" or "strong nuclear force".
There is no electro-static repulsion for neutral particles like neutrons. Baryons -- such as protons and neutrons -- experience an attractive force between each that is very strong but short-ranged. Its name (a not very clever one) is the strong nuclear force. Without this strong force, no elements beyond hydrogen could exist.
Strong force is transmitted by gluons.
The strong nuclear force, aka the strong interaction.
