Relative Density

A body weighs W_(1) gf in air and when immersed in a liquid, it weighs W_(2) gf, while it weighs W_(3) gf on immersing it in water. Find (i) Volume of the body (ii) upthrust due to liquid (iii) relative density of the solid and (iv) relative density of the liqudi.

A wire is suspended vertically from a rigid support. When loaded with a steel weight in air, the wire extends by 16cm . When the weight is completely immersed in Water, the extension is reduced to 14 cm . The relative density of the material of the weight is

A steel wire is suspended vertically from a rigid support. When loaded with a weight in air, it expands by L_(a) and when the weight is immersed completely in water, the extension is reduced to L_(w) . Then relative density of the material of weight is

An object of mass m is submerged completely inside water filled in a container kept on a horizontal surface as shown. The object is tied to the bottom of the vessel by a massless, thin thread. In equilibrium, the tension in the thread is T. The relative density of the object is :

A thin uniform cylindrical shell, closed at both ends, is partially filled with water. It is floating vertically in water in half-submerged state. If rho_c is the relative density of the material of the shell with respect to water, then the correct statement is that the shell is

A U tube contains water and methylated spirts separated by mercury columns in the two arms are in level with 10.0cm of water in one arm and 12.5 cm of spirit in the other. What is the relative density of spirit?

We have two different liquids A and B whose relative densities are 0.75 and 1.0 , respectively. If we dip solid objects P and Q having relative densities 0.6 and 0.9 in these liquids, then

Two spheres of volume 250 cc each but of relative densities 0.8 and 1.2 are connected by a string and the combination is immersed in a liquid. Find the tension T in the string. (g=10m//s^(2))

A cuboidal piece of wood has dimensions a, b and c. its relatively density is d. it is floating in a large body of water such that side a is vertical. It is pushed down a bit and released. The time period of SHM executed by it is

The relative densities of oxygen and carbon dioxide are 16 and 22 ,respectively. If 25cm^(3) of carbon dioxide effuses out in 75s , What volume of oxygen will effuse out in 96s under similar condition?
