Indeed, the reason most objects seem to be neutral is because of how strong the electromagnetic force is! Were it weaker it would be much easier to separate charges on longer length / time scales.
We have gravitational, weak, e/m and strong interaction.
Electromagnetic has the same range, only most objects seem to be neutral.
"Mechanical" force is normally electromagnetic.
The weak force is weak, but not as weak as gravitation (assuming normal charges)
The strong force has indeed short range but is attractive.
