Practice question

Given: The dimensional formula of work is [M L² T^{-2] . What is the dimensional formula of power? These values define the system as per NCERT data. Formula: Power = Work/Time. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: [P] = [M L² T^{-2] / [T] = [M L² T^{-3] . 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.
