From the statements given below: (A) The angular momentum of an electron in n th 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: (a) (B), (C), (D), (E) only (b) (A), (C), (D), (E) only (c) (A), (B), (C), (E) only (d) (A), (B), (C), (D) only

Answer: (c). (A) true: Bohr's quantisation L = nħ. (B) true: nuclear force is short range, not inverse square. (C) true: nuclear force depends on spin. (D) false: nuclear forces are charge independent but non-central. (E) true: smaller packing fraction means a more stable nucleus. So the answer is (c) (A), (B), (C), (E) only.

From the statements given below:

(A) The angular momentum of an electron in $n$ th orbit is an integral multiple of $\hbar$ . (B) Nuclear forces do not obey inverse square law.

(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:

Show answer and solution

Answer: (c)

(A) true: Bohr's quantisation $L = n\hbar$ .
(B) true: nuclear force is short range, not inverse square.
(C) true: nuclear force depends on spin.
(D) false: nuclear forces are charge independent but non-central.
(E) true: smaller packing fraction means a more stable nucleus.
So the answer is (c) (A), (B), (C), (E) only.
