Question

Which physical quantities have the same dimension

• A. Couple of force and work
• B. Force and power
• C. Latent heat and specific heat
• D. Work and power

Answer 1

Answer: (A)

Couple of force and work

Answer 2

Couple of force = $| \vec { r } \times \vec { F } | = \left[ M L ^ { 2 } T ^ { - 2 } \right]$

Work = $[ \vec { F } \cdot \vec { d } ] = \left[ M L ^ { 2 } T ^ { - 2 } \right]$
