Question

The apparent weight of body fully immersed in water is 30 newton and it's weight in air is 96 newton. Calculate the volume of the body.(g=10meter per second and density of water is 100kilogram meter cube)

Answer 1

Point of correction

Density of water is
`1000 Kg/m^(3)` not 100 as provided, it may be typo

Answer:

`0.0066 m^(3)`

Step-by-step explanation:

Buoyant force of water (Weight difference) is 96-30=66 N

Buoyancy force=
`\rho_w g v` where
`\rho_w` is the density of water, g is acceleration due to gravity whose value is provided as
`10 m/s^(2)` and v is the volume of the body

hence substituting 66 for buoyancy force,
`1000 Kg/m^(3)` for density of water and finding the unknown value of volume, v

66=1000*10*v

`v=0.0066 m^(3)`
