II.
$$\mathrm{kg~ms^{-1}}$$

C.
Viscosity
III.
$$\mathrm{kg~m^{-1}~s^{-2}}$$

D.

Choose the correct answer from the options given below :

Accepted Answer

$$
\begin{aligned}
	ext { (A) } 	ext { Surface Tension }=\frac{\mathrm{F}}{\ell} & =\frac{\mathrm{MLT}^{-2}}{\mathrm{~L}}=\mathrm{ML}^{0} \mathrm{~T}^{-2} \\
& =\mathrm{kg\,s}^{-2}(\mathrm{IV})
\end{aligned}
$$
$$
\begin{aligned}
& 	ext { (B) Pressure }=\frac{F}{\mathrm{~A}}=\frac{\mathrm{MLT}^{-2}}{\mathrm{~L}^2} \\
& =\mathrm{kg} \,\mathrm{m}^{-1} \mathrm{~s}^{-2}(\mathrm{III}) 
\end{aligned}
$$
$\begin{aligned} 	ext { (C) Viscosity } & =\frac{\mathrm{F}}{\mathrm{A}\left(\frac{\mathrm{dV}}{\mathrm{dz}}ight)}=\frac{\mathrm{MLT}^{-2}}{\mathrm{~L}^2\left(\frac{\mathrm{LT}^{-1}}{\mathrm{~L}}ight)} \\ & =\mathrm{ML}^{-1} \mathrm{~T}^{-1}=\mathrm{kg} \,\mathrm{m}^{-1} \mathrm{~s}^{-1}(\mathrm{I})\end{aligned}$
$$
\begin{aligned}
	ext { (D) }  	ext { Impulse } & =\int F d t=\mathrm{MLT}^{-2} 	imes \mathrm{T} \\
& =\mathrm{MLT}^{-1}=\mathrm{kg\,ms}^{-1} 	ext { (II) }
\end{aligned}
$$
