The known forces of natures can be divided into four classes, viz., gravity, electromagnetism, week nuclear force and strong nuclear force. With reference to them, which one of the following statements is not correct?

Question

CollectorBabu · Accepted Answer

Correct Answer: Gravity is the strongest of the four.. As per the table shown we see that: Force Strength Gravitational force 10 -39 Weak nuclear force 10 -13 Electromagnetic force 10 -2 Strong nuclear force 1 Gravity has weakest strength, so option A is incorrect. Statement 2 is correct, as Electromagnetism is a science of charge with forces and fields linked with charges. Statement 3 is correct weak force underlies forms of radioactivity that governs the decay of unstable subatomic particles following nuclear fusion reaction. Statement 4 is correct as Strong Nuclear Force hold subatomic particles of nucleus like protons and neutrons. Option A is only incorrect while all three options are correct, so correct is A.
