A light cylindrical vessel is kept on a horizontal surface. Its base area is A.A hole of cross sectional area 'a' is made just at its bottom side. The minimum coefficient of friction necessary for sliding of the vessel due to the impact force of the emerging liquid is `n xx 10 ^(-3).` Find `(a lt lt A).` Given `(a)/(A) = 2 xx 10 ^(-3)`
