Fundamental Forces of Nature

Statement (a) is incorrect. Gravity is NOT the strongest of the four forces - in fact, it is the weakest. The strong nuclear force is the strongest, followed by electromagnetism, then the weak nuclear force, with gravity being the weakest. This is a fundamental principle in particle physics. Statement (b) is correct - electromagnetism acts on electrically charged particles. Statement (c) is correct - the weak nuclear force is responsible for beta decay and radioactivity. Statement (d) is correct - the strong nuclear force binds nucleons together. > The strength order of fundamental forces is: Strong > Electromagnetic > Weak > Gravity. Gravity is the weakest force, not the strongest. Answer: (a).
