NDA General Ability Question (2024) — Solution

Step-by-step solution

1. Gravitational force: This force is fundamental in nature and acts universally between all objects with mass. It governs the motions of planets, stars, and galaxies. 2. Electromagnetic force: This force is also fundamental and governs the interactions between electrically charged particles. It includes forces like attraction between opposite charges (electrostatic force) and interactions involving magnetic fields. 3. Strong and weak nuclear forces: These are fundamental forces that operate at the level of subatomic particles within atomic nuclei. Strong nuclear force: It binds protons and neutrons together in atomic nuclei. Weak nuclear force: It governs processes such as radioactive decay.
