Physics - Fluid Question with Solution | TestHub
In the figure shown, the block of density two times that of water is suspended in water with a string as shown. The coefficient of volume expansion of the solid is one-tenth of that of water. List-I gives the list of certain actions and List-II gives the effects of those actions. Match them.
Column I | Column II |
|---|---|
(P) The system is accelerated upwards with an acceleration of . | (1) The tension in the string increases |
(Q) Another liquid whose density is lesser than that of water and is immiscible in water is poured over the top of water | (2) The tension in the string decreases |
(R) Another liquid whose density is more than that of water but less than the solid and is miscible in water is poured over the top of water | (3) The tension in the string remains the same |
(S) The system is heated up (without change in dimensions of the container) | (4) The pressure at the base of vessel increases |
| (5) The pressure at the base of vessel remains the same |
