In case of a hollow body, if `rho_B` and `rho_S` represent the densities of the body and the substance (of which it is made) respectively, then:

A ball is made of a material of density rho where rho_(oil)ltrholtrho_(water) with rho_(oil) and rho_(water) representing the densities of oil and water, respectively. The oil and water are immiscible. If the above ball is in equilibrium in a mixture of this oil and water, which of the following pictures represents its equilibrium position?

Two solid spheres A and B each of radius R are made of materials of densities rho_A and rho_B respectively. Their moments of inertia about a diameter are I_A and I_B respectively. The value of I_A/I_B is

Assertion: Density of hollows body is always less than the density of substance of equal mass of the body. Reason: Volume of hollow body is greater than the volumeof substance of the body. But mass of hollow body is equal to mass of substance of the body.

If two liquids of same mass but densities rho_1 and rho_2 respectively are mixed, then the density of the mixture is:

If two liquids of same mass but densities rho_1 and rho_2 respectively are mixed, then the density of the mixture is:

If the wt. of a body in vacuum is W and W_1 and W_2 are weights when it is immersed in a liquid of specific gravity rho_1 and rho_2 respectively, then prove that W=(W_1rho_2-W_2rho_1)/(rho_2-rho_1)
