Which physical quantities have the same dimension?

Options

A. Couple and Work
B. Work and Power
C. Force and Power
D. Latent Heat and Specific Heat

Answer

a

Explanation

Couple (or Torque) and Work have the same dimensions. `bartau=Fxxd therefore |tau|=[M^(1)L^(1)T^(-2)xxL^(1)]=[M^(1)L^(2)T^(-2)]` and Work `=[Fxxd]=[L^(2)M^(1)T^(-2)]`
All other pairs of quantities have different dimensions.
