Default A very simple question



I was told that there are four forces in the universe: Strong, Weak,
Electromagnetic, and Gravitational. When I push my finger on the
surface of my desk--Which force is that?

I was told that terea are only three force fields that could be detected:
electric, magnetic and gravitational.

When I push my finger down on the table the electrons on my finger repel
electrons
on the table.
