Question

Among the four fundamental forces, only one force governs your daily life almost entirely. Justify the statement by stating that force.

Answer 1

1. The electromagnetic force is the attractive and repulsive force between electrically charged particles.
2. Since electromagnetic force is much stronger than the gravitational force, it dominates all the phenomena on atomic and molecular scales.
3. The majority of the forces experienced in our daily life like friction, normal reaction, the tension in strings, elastic forces, viscosity, etc. are electromagnetic in nature.
4. The structure of atoms and molecules, the dynamics of chemical reactions etc. are governed by electromagnetic forces.
   Thus, out of the four fundamental forces, the electromagnetic force governs our daily life almost entirely.
