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 pm.01)N` and weight and water is `(5.0 pm 0.1)N`, what would be the maximum percentage error in relative density?

Explanation

`"Relative density"=("weight in air")/("Loss of weight in water")`
Loss of weight in water
`=(10.0-5.0)pm(0.1+0.1)`
`=5.0 pm 0.2 N`
`{:("Percentage error in"),("relative density"):}}={{:("Percentage error in"),("weight in air +"),("Percentage error in"),("loss of weight in water"):}`
`((0.1)/(10.0)+(0.2)/(5.0))xx100=5%`
