Answer & Solution
Correct Answer
(C) (A)-(II), (B)-(IV), (C)-(I), (D)-(III)
Step-by-step Solution
Detailed explanation
(A) \([\mathrm{Y}]=\frac{\mathrm{F}}{\mathrm{A}\left(\frac{\Delta \ell}{\ell}\right)} \Rightarrow \frac{\mathrm{MLT}^{-2}}{\mathrm{~L}^2}=\mathrm{ML}^{-1} \mathrm{~T}^{-2}\) (B) Torque \((\vec{\tau})=\overrightarrow{\mathrm{r}} \times \overrightarrow{\mathrm{F}}\)…
