Practice question

Given: The SI unit of energy is kg m² s^{-2 . What is its dimensional formula? Formula: kg = [M], m² = [L²], s^{-2 = [T^{-2]. Substitution & Calculation: kg m² s^{-2 = [M L² T^{-2] . Final Result: The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
