Question

Consider the following statements about the four fundamental forces in nature (i) The strong nuclear force binds protons and neutrons in a nucleus (ii) The strong nuclear force is about $10^{3}$ times the electromagnetic force in strength (iii) The weak nuclear force is the weakest of all the four fundamental forces (iv) The range of the weak nuclear is about $10^{-16}\, m$ . The correct statement (s) is (are)

• A. (i) only
• B. (ii) and (iii)
• C. (i) and (iv)
• D. (i), (ii) and (iv)

Answer 1

Answer: (A)

(i) only

Answer 2

Since, we know that
Nuclear forces are responsible for keeping the nucleons (neutron and proton) bound in a nucleus. The range of nuclear forces very short $10^{-15}\,m (1-fm)$
Nuclear forces are, one an average much stronger than electromagnetic forces $50-60$ times stronger in their range
Nuclear forces are strongest of all the four fundamental forces
