Which of the following pairs of physical quantites does not have same dimensional formula ?

Options

A. Work and torque
B. Angular momentum and Planck's cosntant
C. Tension and surface tension
D. Impulse and linear momentum

Answer

C

Explanation

[Tension]= [Force] `=[MLT^(-2)]`
[Surface tension] `=(["Force"])/(["Length"])= ([MLT^(-2)])/(L)`
`=ML^(0)T^(-2)`.
