Answer & Solution
Correct Answer
(C) \( A-III, B-IV, C-II, D-I\)
Step-by-step Solution
Detailed explanation
\( F=\eta A \frac{d v}{d y} \) \( {\left[M L T^{-2}\right]=\eta\left[L^2\right]\left[T^{-1}\right]} \) \( \eta=\left[M L^{-1} T^{-1}\right] \) \( S . T=\frac{F}{\ell}=\frac{\left[M L T^{-2}\right]}{[L]}=\left[M L^0 T^{-2}\right] \) \( L=m v r=\left[M L^2 T^{-1}\right] \)…
