Physics - Fluid Question with Solution | TestHub
A bottle is filled with water, above which a little air at atmospheric pressure is present. Plugs are blocking the three small holes (A, B & C). (Hole B is just below the upper most layer of water)
Column-I | Column-II |
|---|---|
(A) A and C are opened | (P) Air comes into the bottle from upper most open hole |
(B) B and C are opened | (Q) Water flows out of holes B and C |
(C) Only C is opened | (R) Very little water comes out and the flow stops |
(D) All the holes are opened | (S) Pressure of air inside bottle above the water remains unchanged. |
Options:
Answer:
Solution:
With A and C open, air enters at A and water leaves through C: A matches P and S.
With B and C open, the printed matching is B with P and Q.
With only C open, a little water leaves before the pressure difference stops the flow: C matches R.
With all three open, the source key pairs D with P, Q and S.
