Which physical quantity has dimensions equal to [M L^2 T^-2]?
A. Force
B. Pressure
C. Work and Energy✓ Correct Answer
D. Power
💡 Solution & Explanation
Work and energy share the same dimensional formula of M L squared T to the power of negative two, as work is calculated as the scalar product of force and displacement. Force possesses the dimensions of M L T to the power of negative two, whereas pressure incorporates an area term in the denominator.
