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.

A

`5.00 pm 0.05 `

B

`5.00 pm 11%`

C

`5.00 pm 0.10 `

D

`5.00 pm 6%`

Text Solution

Verified by Experts

The correct Answer is:
B
Relative density = `("Weight in air")/("Loss of weight in water")`
`P = (5.00)/(1.00) = 5.00`
`(dp)/(P) = (0.05)/(5.00) + (0.1)/(1.00) = 0.11 = 11%`
`P = 5.00 pm 11%`

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
