From the statements given below : (A) The angular momentum of an electron in n^th orbit is an integral multiple of h. (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 :
- (A), (B), (C), (D) only
- (B), (C), (D), (E) only
- (A), (C), (D), (E) only
- (A), (B), (C), (E) only
Correct answer: (A), (B), (C), (E) only
Solution
The correct option includes statements that accurately describe fundamental principles of quantum mechanics and nuclear physics. Specifically, the angular momentum quantization in orbits, the nature of nuclear forces not following the inverse square law, their spin dependence, and the relationship between stability and packing fraction are all valid concepts in these fields.
