Quizplus · Accepted Answer

The electromagnetic force is responsible for holding atoms together in a block of wood. This force acts between electrically charged particles such as protons and electrons, and it is the force that holds atoms and molecules together to form solid objects. The other fundamental forces (gravitational, weak nuclear, and strong nuclear) are not relevant on this scale.
