Questions
A light cylindrical vessel is kept on a horizontal surface. It’s base area is A. A hole of cross sectional area a is made just at its bottom side. The minimum coefficient of friction necessary to stop sliding of the vessel due to impact force of the emerging liquid is (a << A).
detailed solution
Correct option is C
Velocity of efflux = 2ghForce =av2ρ=a2ghρi.e., equal to frictional force a2ghρ=μmg=μAhρgμ=2aATalk to our academic expert!
