The relative density of material of a body is found by weighting it first in air and then in water . If the weight in air is `( 5.00 +- 0.05) N` and the weight in water is `(4.00 +- 0.05) N`. Find the relative density along with the maximum permissible percentage error.

The relative density of a material of a body is found by weighing it first in air and then in water. If the weight of he body in air is W_(1) = 8.00 +- N and the weight in water is W_(2) = 6.00 +- 0.05 N , then the relative density rho_(r ) = W_(1)//( W_(1) - W_(2)) with the maximum permissible eror is

The relative density of a material is found by weighing the body first in air and then in water . If the weight in air is ( 10.0 +- 0.1) gf and the weight in water is ( 5.0 +- 0.1) gf , then the maximum permissible percentage error in relative density is

A body weight 20 N in water and its relative density is 3. Find the weight of the body in air.

A metal block having an internal cavity weight 110 g in air and 80 g in water. If the density of metal is 5.5 g//cc, then the volume of cavity is :

A body weight 5 N in air and 2 N when immersed in a liquid. The buoyant force is

The weight of a body in water is one third of its weight in air. The density of the body is

The weight of a body in air is 50 N. When the same body is weighed in water its weight decreases by 5N. Calculate the density of the given body.
