Which of the following pairs does not have same dimensions?

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.

Q3 Single Correct Medium
A student performs an experiment to determine the Young's modulus of a wire, exactly $2\ m$ along. by Searle's method. In a particular reading, the student measures the extension in the length of the wire to be $0.8\ mm$ with an uncertainty of $0.05\ mm$ at a load of exactly $1.0\ kg$. The student also measures the diameter of the wire to be $0.4\ mm$ with an uncertainty of $0.01\ mm$. Take $g = 9.8\ ms^{-2}$ (exact). The Young's modulus obtained from the reading is
• A. $(2.0\pm 0.3) \times 10^{11} N\ m^{-2}$
• B. $(2.0\pm 0.2) \times 10^{11} N\ m^{-2}$
• C. $(2.0\pm 0.1) \times 10^{11} N\ m^{-2}$
• D. $(2.0\pm 0.05) \times 10^{11} N\ m^{-2}$
