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

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

A solid weights 32 gf I air and 28.8 gf in water. The R.D. of the solid is

A sphere has mass of (20+-0.4)kg and radius of (10+-0.1) m. Find the maximum percentage error in the measurement of density.

The mass and volume of a body are found to be 5.00 pm 0.05 kg " and "1.00 pm 0.05 m^3 respectively. Then, the maximum possible percentage error in its density is

A body weight 20 N in a liquid whose relative density is 5. In water it weight 40 N. Find its weight in air ?

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

The density of a material in the shape of a cube is determined by measuring three sides of the cube and its mass. If the relative errors in measuring the mass and length are respectively 1.5% and 1% , the maximum error in determining the density is:
