Question
What are the correct dimensions of work and acceleration?
Correct Answer
Option D is the correct answer.
Detailed Explanation
Work = force × distance = (mass × acceleration) × distance = (M × LT⁻²) × L = ML²T⁻². Acceleration = velocity/time = LT⁻¹ / T = LT⁻². Therefore, work has dimensions ML²T⁻² and acceleration has dimensions LT⁻².
Hint
Recall the definitions: work = force × displacement, acceleration = change in velocity per time.
