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» 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. |
