Which of the following fundamental forces in nature has the weakest relative strength?

💡 Solution & Explanation

Gravitational force is vastly weaker than electromagnetic, weak nuclear, and strong nuclear forces, making it the weakest among the four fundamental forces despite governing large-scale astronomical structures. The strong nuclear force holds quarks and nucleons together and reigns as the strongest. Candidates must remember the descending order of fundamental force strengths: strong nuclear, electromagnetic, weak nuclear, and gravitational.
