Practice question

Given: A force F = 6x² N acts from x = 0 to x = 1 m . What is the work done? Formula: Work W = int_0¹ 6x² dx = [ 2x³ ]_0¹ = 2 × 1 - 0 = 2 J .. Substitution: Substituting given values into formula as per NCERT 2026-27 method. Calculation: Simplifying step by step with proper SI units like m/s², J kg⁻¹ K⁻¹, 10⁻⁵, A m⁻¹ etc. Final Result: The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
