Practice question

Given: What is the volume of a nucleus with radius 3.0 × 10⁻¹⁵ m ? (Use π = 3.14 ) These values define the system as per NCERT data. Formula: Volume = 4/3 π R³. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: R³ = (3.0 × 10⁻¹⁵)³ = 2.7 × 10⁻⁴⁴ m³ . Volume = 4/3 × 3.14 × 2.7 × 10⁻⁴⁴ approx 1.13 × 10⁻⁴³ m³ . Result: The computed value matches the expected outcome and confirms the correct choice. Units and powers like J kg⁻¹ K⁻¹, m/s², 10⁻⁵ are properly used as per NCERT.
