JEE Main 2024 Physics question
From the statements given below: (A) The angular momentum of an electron in n orbit is an integral multiple of ℏ. (B) Nuclear forces do not obey inverse square law. (C) Nuclear forces are spin dependent. (D) Nuclear forces are central and charge independent. (E) Stability of nucleus is inversely proportional to the value of packing fraction. Choose the correct answer from the options given below:
Answer: (D)
Solution
Nuclear forces are non-central (they have a tensor part), so (D) is false; the other four statements are true.
