Practice question

Given: What is the SI unit of a quantity with dimensional formula [M L² T^{-3 A^{-1] ? These values define the system as per NCERT data. Formula: [M] = kg, [L] = m, [T] = s, [A] = A. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: [M L² T^{-3 A^{-1] = kg m² s^{-3 A^{-1 . (Matches electric potential: Volt = W/A = kg m² s^{-3 A^{-1 ). 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.
