$\begin{aligned} & {[\mathrm{Y}]=\frac{F}{A} \cdot \frac{\Delta L}{L}=\frac{M L T^{-2}}{L^2}=\mathrm{ML}^{-1} \mathrm{~T}^{-2}} \\ & \mathrm{~F}=6 \pi \eta \mathrm{r} v \\ & {[\eta]=\frac{\mathrm{F}}{6 \pi \mathrm{rr}}=\frac{\mathrm{MLT}^{-2}}{\mathrm{~L} \mathrm{LT}^{-1}}} \\ & {[\eta]=\mathrm{ML}^{-1} \mathrm{~T}^{-1}} \\ & {[\mathrm{~h}]=\frac{\mathrm{E}}{\mathrm{f}}=\frac{\mathrm{ML}^2 \mathrm{~T}^{-2}}{\mathrm{~T}^{-1}}=\mathrm{ML}^2 \mathrm{~T}^{-1}} \end{aligned}$
Work function $\left ( \phi \right )= ML^{2}T^{-2}$
