Practice question

Given: The dimensional formula of energy density is [M L^{-1 T^{-2] . What is the dimensional formula of energy flux (energy per unit area per unit time)? Formula: Energy flux = Energy / Area / Time. Substitution & Calculation: [M L² T^{-2] / [L²] / [T] = [M L² T^{-2] [L^{-2] [T^{-1] = [M T^{-3] . Final Result: The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
