Question

A mass less conical flask filled with a liquid is kept on a table in a vacuum. The force exerted by the liquid on the base of the flask is W₁. The force exerted by the flask on the table is W₂.

(a) W₁ = W₂ 

(b) W₁ > W₂ 

(c) W₁ < W₂ 

(d) The force exerted by the liquid on the walls of the flask is (W₁ - W₂).

Answer 1

Correct Answer is: (b) W₁ > W₂ (d) The force exerted by the liquid on the walls of the flask is (W₁ - W₂).

Pressure acts equally in all directions, and a liquid exerts forces on the walls of its container normal to the walls. Hence, the liquid exerting forces on the sloping walls of the conical flask will have a net upward component.
