A light cylindrical vessel is kept on a horizontal surface. Area of base is A. A hole of cross-sectional area ' $\displaystyle a$ ' is made just at its bottom side. The minimum coefficient of friction necessary to prevent sliding the vessel due to the impact force of the emerging liquid is $\displaystyle (\mathrm{a} \ll \mathrm{A})$ :
Official answer
(2)
$\displaystyle \frac{2 \mathrm{a}}{\mathrm{~A}}$
