Practice question

Given: The dimensional formula of momentum is [M L T^{-1] . What is the dimensional formula of impulse? These values define the system as per NCERT data. Formula: Impulse = Force × Time. This is the standard NCERT relation for this phenomenon. Substitution & Calculation: [F] = [M L T^{-2], [t] = [T] . [Impulse] = [M L T^{-2] [T] = [M L T^{-1], same as momentum. 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.
