Correct Option is (D) \([ML^{-1}T^{-1}]\)

We know that ,

\(F = \eta A \left(\frac{dv}{dx}\right) \)

where,

F = Force

A = Area

\(\eta\) = cofficient of viscosity

dv = velocity change by dx

\(\eta = \frac{F}{A} \left(\frac{dx}{dv}\right)\)

\(\eta\) = \(\frac{[MLT^{-2}][L]}{[L^2][LT^{-1}]}\)

\(\eta = [ML^{-1}T^{-1}]\)
