Q. 6

Which of the foll A. Work and torque .

B. Angular momentum and Planck’s constant.

C. Tension and surface tension.

D. Impulse and linear momentum.

Answer :

Most physical quantities can be expressed in terms of combination of five basic dimensions. These are,


1.mass(M)


2.length(L)


3.time(S)


4.electrical current(I) and,


5.temperature ()


For,


(a) Work and torque



From the table above we can see that only pair having different dimensional formula is tension and surface tension.
