If V₁ and V₂ be the volumes of the liquids flowing out of the same tube in the same interval of time and n₁ and n₂ their coefficients of viscosity respectively, then

• A

  $\frac{{\mathrm{\eta }}_1}{{\mathrm{\eta }}_2}=\frac{{\mathrm{V}}_2}{{\mathrm{V}}_1}$

• B

  $\frac{{\mathrm{\eta }}_1}{{\mathrm{\eta }}_2}=\frac{{\mathrm{V}}_1}{{\mathrm{V}}_2}$

• C

  $\frac{{\mathrm{\eta }}_1}{{\mathrm{\eta }}_2}=\frac{{\mathrm{V}}_1^2}{{\mathrm{V}}_2^2}$

• D

  $\frac{{\mathrm{\eta }}_1}{{\mathrm{\eta }}_2}=\frac{{{\mathrm{V}}_2}^2}{{{\mathrm{V}}_1}^2}$
