Physics

Which of the following pairs does not have same dimensions?


ANSWER

moment of inertia and moment of force


SOLUTION
Moment of force  $$(\tau)$$ is equal to the product of moment of inertia $$(I)$$ and the angular acceleration $$(\alpha)$$ of the rotating body.
$$\therefore$$       $$\tau  = I \alpha$$
Hence  the dimensions of moment of force and moment of inertia must be different.
