A body weigh `50 g` in air and `40 g` in water. How much would it weigh in a liquid of specific gravity `1.5`

65 grams

45 grams

30 grams

35 grams

Text Solution

Verified by Experts

The correct Answer is:

`50g=Vxxrho=50,V(rho-1)=40`.
`V(rho-1.5)=? Vrho=50`.
`50-V=40,V=10c c`.
`10xxrho=50,rho=5g//c c`,
Weight in a liquid of specific gravity (1.5)
`=10xx3.5=35`gm.

The relative density of a material of a body is found by weighing it first in air and then in water. If the wt. of the body in air is W_(1)=8*00+-0*05 newton and weight in water is W_(2)=6*00+-0*05 newton. Then the relative density, p_(r)=(W_(1))/(W_(1)-W_(2)) with the maximum permissible error is :
