List of top Physics Questions on Nucleus asked in NEET (UG)

एक सरल लोलक के गोलक की गतिज ऊर्जा और स्थितिज ऊर्जा का योग 0.02 जूल है। साम्य (संतुलन) स्थिति पर, सरल लोलक के गोलक की चाल लगभग है: (मान लीजिए गोलक का द्रव्यमान = 20 g)

An unknown nucleus has a nuclear density of 2.29 $\times$ 10¹⁷ kg/m³ and mass of 19.926 $\times$ 10⁻²⁷ kg. Its mass number A is approximately: (Take $R_0 = 1.2 \times 10^{-15}$ m, $4\pi = 12.56$)

Four statements are given (A is mass number):
A. The volume of a nucleus is proportional to A.
B. The volume of a nucleus is proportional to A$^{1/3$.}
C. The difference in mass of an atom and its nucleus is called the mass defect.
D. The difference in mass of a nucleus and its constituents is called the mass defect.
Choose the correct answer from the options given below:

एक अज्ञात नाभिक का, नाभिकीय घनत्व 2.29 × 10¹⁷ kg/m³ और द्रव्यमान 19.926 × 10⁻²⁷ kg है। उसकी द्रव्यमान संख्या A लगभग है:
(R₀ = 1.2 × 10⁻¹⁵ m, 4π/3 ≈ 4.19 लीजिए) (Note: The OCR is slightly garbled, but the context is clear. Using 4π/3 ≈ 4.19 which is a more standard approximation than 12.56)
