Choose the pairs of quantities which have same dimensions : Impulse, force, work, momentum, moment of force, tension.

Answer:

                (i) Impulse and momentum have the same dimensions : \[\left[ {{\text{M}}^{\text{1}}}{{\text{L}}^{1}}{{T}^{-1}} \right]\] (ii) Force and tension have the same dimensions : \[\left[ {{\text{M}}^{\text{1}}}{{\text{L}}^{1}}{{T}^{-2}} \right]\]. (iii) Work and moment of force have the same dimensions : \[\left[ {{\text{M}}^{\text{1}}}{{\text{L}}^{2}}{{T}^{-2}} \right]\].
