The weight of a constant immersion hydrometer is 15 gwt. When it is immersed in a liquid, few more lead shots were added to it so that it floats at the same depth as in water. If the weight of the hydrometer now is 20 gwt, find its relative density.

The depth of immersion of hydrometer in water is 10 cm. What will be the depth of immersion in a liquid whose density is 2 g cm^(-3) ?

A constant immersion hydrometer floats vertically in water when the weight of its float is 30 g. When it is made to float in a liquid (miscible in water), the weight of its float is increased by 10 g. Find the weight of the hydrometer when it is floated in a mixture containing equal masses of water and the liquid.

When an object of weight W is immersed in a liquid, its weight in the liquid is found to be W_(1) . When it is immersed in water, the weight of the displaced if found to be W_(2) . The relative density of the liquid is

A density bottle weighs 100 g when filled with liquid annd 80 g when filled with water. If the weight of an empty density bottle is 20 g, find the density of the liquid.

A body is immersed in a liquid of relative density 2.6. It is found that the weight of the body in the liquid is two-thirds of its weight in air. Calculate the density of the body ?
