A thin uniform cylindrical shell, closed at both ends, is partially filled with water. lt is floating vertically in water in half-submerged state. lf ρc​ is the relative density of the material of the shell with respect to water, then the correct statement is that the shell is A thin uniform cylindrical shell closed at [...]

A log of wood of mass 120 kg floats in water. The weight that can be put on the raft to make it just sink, should be (density of wood = 600 kg/m^3) A log of wood of mass 120 kg floats in water. The weight that can be put on the raft to make [...]

A solid sphere of density a(>1) times lighter than water is suspended in a water tank by a string tied to its base as shown in the fig. If the mass of the sphere is m then the tension in the string is given by: A beaker containing a liquid of density ρ moves up [...]

A vertical U-tube contains a liquid. The total length of the liquid column inside the tube is l. When the liquid is in equilibrium, the liquid surface in one of the arms of the U-tube is pushed down slightly and released. The entire liquid column will undergo a periodic motion. A vertical U-tube contains a [...]

A sealed tank containing a liquid of density ρ moves with horizontal acceleration a as shown in the figure. The difference in pressure between the points A and B is A sealed tank containing a liquid of density ρ moves with horizontal acceleration a as shown in the figure. The difference in pressure between the [...]

A U-tube containing a liquid moves with a horizontal acceleration a along a direction joining the two vertical limbs. The separation between these limbs is d. The difference in their liquid levels is A U-tube containing a liquid moves with a horizontal acceleration a along a direction joining the two vertical limbs. The separation between [...]
