Two cylinders of same cross-section and length L but made of two different materials of densities `d_(1)` and `d_(2)` are cemented together to from a cylinder of length 2L. The combination floats in a liquid of density `d " " d_(1) lt d_(2)` then

If equal masses of two liquids of densities d_(1) and d_(2) are mixed together, the density of the mixture is

If equal masses of two liquids of densities d_(1) and d_(2) are mixed together, the density of the mixture is

A cylindrical block of length 2l is made of two different materials. The uppwer half has density d_(1) and and lower half, which is heavier, has density d_(2) the block is floating in a liquid of unknown density d with (l)/(2) of its length outside the liquid. (a) Find d (b) Show that dgt(4d_(1))/(3)

Weight of a body on the surfaces of two planets is the same. If their densities are d_(1) and d_(2) , then ratio of their radii is
